meshtastic_jtag

An easy to assemble JTAG debugging PCB for meshtastic image

Features

  • Works with any ESP32 Devkit C compatible board
  • Support for OLED (front) and GPS (back)
  • Compatible with ebyte e22-900m22s LORA module
  • Built in 915MHz monopole antenna

Project status

  • Gerbers are not tested and schematic has not been reviewed
  • Antenna matching network needs to be optimized

Assembly instructions

  • Gerber files are in the /gerber/ directory, they are plotted in a format that can be directly uploaded to JLPCB
  • When ordering from JLCPCB don't forget to tick "specify a location" under "remove order number" so that the JLC PCB number is at the PCB back side
  • Assembly should be pretty self-explanatory, minimum hardware requirement is the ESP32 Devkit and the e22-900m22s LORA module with the two decoupling capacitors
  • OLED display goes on the PCB front side
  • NEO6M GPS module goes on the PCB back side
  • The matching network needs fine tuning, for now you should not place C3 and C4 and add a short in place of L1 (small blob of solder)
