BrewPi Remix Rotary Encoder Breakout

Rotary Encoder Breakout v1.0

A breakout board to provide pins for connecting the rotary encoder to the BrewPi controller. Designed for CUI, ACZ11BR1E-15FD1-20C or similar footprint. Despite the picture linked on that page, you want a vertical mounting encoder (and that one really is.) You don't really need this, but it will surely make it easier to connect things with Dupont wires.

BOM:

• 1 each PCB (this project)
• 1 each Four-pin 2.54mm Dupont header, male or female according to your preference.
• 1 each CUI Rotary Encoder ACZ11BR1E-15FD1-20C - You want a magnetic encoder with a vertical shaft, no pull-ups, and 20 detents
• 1 each Rotary Knob

BrewPi ESP8266 - No LCD v0.2

ESP8266 - Through Hole w/o LCD

This PCB is designed to allow connecting an ESP8266 to the other hardware necessary to run the BrewPi firmware and control fermentation temperatures for your brewery. This specific board was designed to use a LoLin D1 Mini ESP8266 microcontroller and integrate with a 2-channel relay board. It does NOT support an LCD screen. This PCB supports the use of dupont connectors for connecting the relay which allows for a much more compact design than if screw terminals were used.

This board does not have terminals for directly connecting temperature sensors - it is intended to have an RJ-45 jack soldered on, and then be connected to a separate RJ-45 sensor board via an ethernet cable.

BrewPi ESP8266 - LCD TH Dupont v0.2

ESP8266 - Through Hole /w LCD & Dupont PCB

This PCB is designed to allow connecting an ESP8266 to the other hardware necessary to run the BrewPi firmware and control fermentation temperatures for your brewery. This specific board was designed to use a LoLin D1 Mini ESP8266 microcontroller and integrate with a 2-channel relay board and a LCD2004 IIC LCD screen. This PCB supports the use of dupont connectors for connecting the relay and IIC LCD which allows for a much more compact design than if screw terminals were used. This PCB uses a "SparkFun"-style level shifter module for handling the level conversion necessary to drive the LCD display.

This board does not have terminals for directly connecting temperature sensors - it is intended to have an RJ-45 jack soldered on, and then be connected to a separate RJ-45 sensor board via an ethernet cable.

BrewPi ESP8266 - LCD TH Screws v0.2

ESP8266 - Through Hole /w LCD & Screw Terminal PCB

This PCB is designed to allow connecting an ESP8266 to the other hardware necessary to run the BrewPi firmware and control fermentation temperatures for your brewery. This specific board was designed to use a LoLin D1 Mini ESP8266 microcontroller and integrate with a 2-channel relay board and a LCD2004 IIC LCD screen. This PCB supports the use of screw terminal connectors for connecting the relay and IIC LCD which some builders find to be easier to use due to their larger size.

This board does not have terminals for directly connecting temperature sensors - it is intended to have an RJ-45 jack soldered on, and then be connected to a separate RJ-45 sensor board via an ethernet cable.

RJ-11 Sensor Breakout Board v1.1

RJ-11 Sensor Breakout

NOTE - For new builds, the use of the RJ-11 boards are not recommended. The RJ-45 boards are recommended instead.

This board is intended to allow for the DS18b20 temperature sensors (and optionally, door switch) to be connected to a PCB that is away from your main BrewPi controller, thereby allowing for the use of shorter temperature sensor cables - or for the placement of the sensor breakout inside your fermentation chamber if necessary. This breakout board is intended to be connected to the BrewPi controller via an RJ-11 straight-through cable.

Be very careful when choosing a cable to connect your sensor board to your BrewPi controller - not all RJ-11 cables are straight through

Temperature sensors are intended to be soldered directly to the board, and the door sensor can either be soldered directly to the board or can be connected via an optional screw terminal.

RJ-45 Sensor Breakout Board v1.1

RJ-45 Sensor Breakout

This board is intended to allow for the DS18b20 temperature sensors (and optionally, door switch) to be connected to a PCB that is away from your main BrewPi controller, thereby allowing for the use of shorter temperature sensor cables - or for the placement of the sensor breakout inside your fermentation chamber if necessary. This breakout board is intended to be connected to the BrewPi controller via an RJ-45 straight-through cable (i.e. Ethernet).

Temperature sensors are intended to be soldered directly to the board, and the door sensor can either be soldered directly to the board or can be connected via an optional screw terminal.

RJ-45 Sensor Breakout

Breakout Board for the BrewPi Remix Project

This optional breakout board is intended to be connected to the Arduino Shield v1.3.1a via a straight-through RJ45 terminated cable (i.e. an Ethernet cable.) It allows the Arduino to be located remotely from the fermentation chamber.

Supported Features:

• Door switch
• Heat/Cool
  • Dupont pins
  • Screw terminal
• Heat/Cool LEDs
• Temp Sensors
  • Three Dupont pin sets
  • Three screw terminals

Usage Notes:

Since this board is intended to support multiple configurations, some customization during assembly is required.

• Heat / Cool LEDs - You will use different connections for LEDs depending on the configuration of your actuators. Connections are provided for two LEDs each for heat and cool, however you will only use one based on your setup
  • Inverted (typical for relay board) - Connect the LED between VCC and the center pin. A resistor is not needed as there is one on the board
  • Non-Inverted (typical for SSRs) - Connect the LED between the center pin and GND. A resistor is not needed as there is one on the board

BOM:

• 1 ea Red 3mm LED
• 1 ea Blue 3mm LED
• 2 ea 220Ω 1/4W Axial Resistors
• 1 ea 4-Pin header
• 1 ea 2-Pin header
• 3 ea 3-Pin headers

Arduino Uno shield for BrewPi Remix

Arduino Uno shield for the BrewPi Legacy Remix project.

This is an new board design which incorporates an I2C LCD header in addition to the original parallel LCD header on the RevC. The I2C display is supported in version 0.5.3 of BrewPi Legacy Remix Scripts, WWW and Tools, coupled with version 0.2.12 of the Arduino Firmware.

Supported Features:

• Wireless to Serial Bridge (Bluetooth or ESP8266 module)
• Door switch
• Alarm
• Heat/Cool Relay
• Rotary Encoder w/Pushbutton
• Heat/Cool LEDs
• OneWire Selector A0/A4 (required for I2C)
• Three OneWire connections
• I2C LCD; or;
• Parallel LCD
• RJ45 connector includes support for:
  • OneWire
  • Door Switch
  • Heat/Cool Relay
• All Arduino headers available

Usage Notes:

Since this board is intended to support both the RevC as well as the I2C firmware, some configuration is required via jumper caps.

• ONE_WIRE_SEL Jumper - If you do not select the proper configuration, you may not be able to configure the OneWire sensors, the display may fault, or both.
  • Jump between A4 and the center pin for RevC
  • Jump between A0 and the center pin for I2C
• Backlight Timeout - If you do not have a rotary encoder you will not be able to wake the backlight if it times out. You can configure the board to never turn off the backlight
  • RevC - The BACKLIGHT jumper has two settings:
    • Jump between ON and the center pin to have the backlight stay on
    • Jump between PB and the center pin to have the backlight time out
  • I2C - The backlight setting uses the rotary encoder header
    • If you have a rotary encoder, pushing the button during a controller reset will disable backlight timer
    • If you do not have a rotary encoder, adding a jumper on the ROT_ENC header between PSH and GND will disable backlight timer
• Heat / Cool LEDs - You will use different connections for LEDs depending on the configuration of your actuators
  • Inverted (typical for relay board) - Connect the LED between VCC and the center pin. A resistor is not needed as there is one on the board
  • Non-Inverted (typical for SSRs) - Connect the LED between the center pin and GND. A resistor is not needed as there is one on the board

Bill of Materials

General Parts

Since this uses 1 or 2 each of very common, very inexpensive components, you may find you are better off buying a resistor assortment for instance or end up buying 10 or 20 at a time. Make several!

This BOM is available on Mouser via this link.

Other Parts

Optional Parts

The items marked with an *asterisk above are optional. They are in the design to provide a means to monitor and trend one's ambient temperature where the fermenter is placed, and/or the fermenting liquid's temperature via a thermowell or insulated in contact with the fermenter. If one chooses not to use these, the firmware will automatically skip reporting these readings.

iot_lora_v4.2

This design (a RFM95W controlled by an Arduino Pro Mini) was my first step in the world of IoT.

The board is tested with the examples of the Matthijs Kooijman
LMIC library and works perfect.

It's also used in the IoT workshop
LoraWAN Grundlagen
of the iot-usergroup.de.

A second set of PCB designs (power supply/sensor boards) are planned as piggyback/hat for this
iot_lora board. Power alternatives will be: solar cell, CR2032, 2 x AAA, supercap, TPS61291,
TPL5111 and/or TPS22860.

BOM
1 x RFM95w/868MHz
1 x Arduino Pro mini
2 x 10K (I2C pull up)
1 x SMA antenna connector
1 x pin header 2x7

ATTENTION: The update to V2.0: ADC6 and ADC7 (analog exclusively) are not connected
to JP3 anymore but PB0 and PB1 (possibility for soft serial). The HF part has now a switch to SMA
or spring antenna and added are GND planes on both sides.

ATTENTION: The update to V3.0: (on request) added a JST PH 2mm power connector
(for RAW and VCC) and a silkscreen update.

ATTENTION: The update to V4.0: added the footprint (SOP-8) for AT24CXX EEPROM to save TTN EUI's and Key's.

ATTENTION: The update to V4.2: added footprints for 2 x IPEX-Connector and extra debug LED (D1) on 10.
