iot_lora_wifi_esp12_v1.1

This design (a RFM95W controlled by an ESP12F) is intended as direct replacement for the iot_lora_v4.2
board (same form-factor, same interface connector).

The board is tested with the Arduino IDE and the
MCCI LoRaWAN LMIC library mcci-catena/arduino-lmic
(see also:
IBM LoRaWAN in C (LMiC)
).
and works perfect.

A second set of PCB designs (power supply/sensor boards) are already designed and tested or planned as
piggyback/hat for this iot_lora_wifi_esp12 board. Power alternatives will be: solar cell, CR2032, 2 x AAA,
supercap. Controlled by: the TPS61291, TPL5111 and/or TPS22860.

1 x RFM95w/868MHz
1 x ESP12F
2 x 10K (I2C pull up)
1 x SMA antenna connector
1 x pin header 2x7

ATTENTION: The update to v1.1: added a reset button for more flash comfort.

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 - 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-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

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

Brew Bubbles Shield v1.0

This shield provides the necessary component connections and circuitry for the Brew Bubbles project. It is nearly identical in size to the Wemos D1 mini we use to provide a very compact and lightweight footprint.

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 already designed and tested or planned as
piggyback/hat for this iot_lora_wifi_esp12 board. Power alternatives will be: solar cell, CR2032, 2 x AAA,
supercap. Controlled by: the 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.

Auto light

Attiny10 & APDS-9930 based automatic light/switch

https://github.com/N-Storm/autolight

https://easyeda.com/NStorm/autolight-board

This project utilizes small ATtiny10 mcu to work with APDS-9930 ambient light (AL) and proximity I2C sensor.
This is used for automatic "smart" light in a drawer. Once the drawer are open the APDS-9930 will notice proximity change
and trigger a preset interrupt and MCU will come from sleep to check if AL level are below set (i.e. it's dark around).
If the set condition for AL level will be met, it will enable HIGH level on PB3 pin. Which is connected to a MOSFET or any other switch to enable LED light.

Reset shares same PB3 pin so it must be disabled via fuses. You will have to apply +12V to PB3/RESET pin to reprogram attiny10 after flashing RSTDISBL fuse.

The PB2 port are used as INT0 for sensor interrupts to wake MCU from sleep on proximity change event.

Building

Fetch the latest trunk:

git clone https://github.com/N-Storm/autolight && cd autolight

Then tweak some settings in autolight.h if required. They are commented. After that do a:

make && make flash && make fuse.

:warning: After you do a make fuse step, you won’t be able to program MCU again without applying +12V to RESET pin (make sure it’s not connected to your programmer hardware :warning:

Alternatively you can use pre-built binaries with the default settings from releases section.

Connecting

PB0 ↔ SCL

PB1 ↔ SDA

PB2 ↔ INT

PB3 are the module digital output, with logic LOW when light should be turned off and HIGH when it should be on. Suited for connecting to an N-channel FET driving the LED light.

Please be aware that the APDS-9930 module requires 2.5 – 3.6 V for it’s operation on Vdd+Vbatt (IR LED power). I recommend to use a 3.3V LDO for powering both MCU & APDS-9930.

Schematics & board are available on EasyEDA: https://easyeda.com/NStorm/autolight-board

:warning: This board has two places for LDOs - U3 & U4. Solder only one of them! :warning:

They replace each other. The board are made so they could replace each other. Alternatively edit board/schematics to replace them with your favorite LDO.
