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.

BOM
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.

MEGA_programmer

E(E)PROM (2708..27512) programmer. Piggy Back for Arduino Mega 2560. Design is not ready and tested yet.

NanoPiCore4Dinbox

NanoPiCore4DinBox is a board that allows the integration of a Nano Pi Neo Core/Core2 in a DIN box.

The dimensions of the board are provided for a CAMDENBOSS CNMB series box.

This provides ETH and USB interfaces and 6 LEDs on the front of the box (or 4 LEds and 1 push-button).

The NanoPiCore4DinBox board is installed vertically in the box and connected to the NanoPiCore by the GPIO3 connector on the backplane board.

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

RJ45-connected breakout board for use with the Wemos D1 Mini 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
