  • Weekend on the Dark Side

  • Put jumper, connect assembly to battery, quickly check voltage on ESP board. Must be close to 3.3V and stable. Attach TTL serial cable, flash software. Disconnect battery, remove jumper, connect battery.It should work now.
  • PolaPi v2.0

  • TTL cable modificationcut off the green wire of the TTL Printer or just remove it, use a thin screw driver to unplug it (if you run the printer with 7,4V and attach the Tx to the GPIO of the Raspberry you can damage it, so as it is not needed we unplug/cut...
  • Connect to Arduino

  • Plug the collated ground wires into the Arduino Ground pin, and plug the other jumper wires into the correct I/O pins: Toggle switch - 0 Pilot LED - 1 TTL output - 2 Rotary switch 1 (ontimes) - 3, 4, 5, 6, 7 Rotary switch 2 (frequency) - 8, 9, 10, 11,...
  • Instructions

  • Assembly components on the PCB per schematics.All TTL chips and components can be soldered directly on PCB.*Recommended to install EEPROM chip U3 on a DIP 24 pin socket, so that EEPROM could be easily removed and reprogrammed when needed.*Note: U10 chip...

  • K30 CO2 sensor (optional):The CO2 sensor is very simple, and works over TTL serial. Hook up the K30 (no extra components needed), making sure to cross rx and tx wires.Test out your CO2 sensor by running the k30.py in the code to take a CO2 sample.Make...
  • Connect things together

  • Connect the Pi to the GPS sensor and the FPV transmitter.Depending on the voltage level, the GPS sensor might need to be connected directly to the Pi without TTL converter. Connect the Pi to the Camera module.FPV transmitter and the Pi might be...
  • Simple Edison Breakout Board

  • Simple UART level converter.As I'm sure you are aware, the Edison is 1.8v gpio only so you either need to get a 1.8v TTL USB Cable or you can use a 3.3v or 5v Arduino style TTL USB cable, but it will need a shift level to achieve this.So a simple design...

  • At this point you need to make a decision, either build your relay circuit, or buy it. I bought one for fairly cheap ($7) that had 4 relays on it. SainSmart relay. You also need to get some magnetic proximity sensors. Most of these will work.
  • Connections To Arduino

  • BABYDUNO is Compatible With Arduino IDE. We shall use Arduino UNO as USB to TTL Converter and Upload Program using Arduino As ISP. Connections: D10 of Arduino to Reset of BABYDUINO D11 of Arduino to PB0 of BABYDUINO D12 of Arduino to PB1 of BABYDUINO...
  • Material Preparation

  • Prepare one ESP32-CAM / one FTDI USB to TTL Serial Converter / one mini USB to USB converter / 4 wires Connect your ESP32-CAM to Serial Converter with the following picture:
