Gory details of my next build: a small meshcore repeater intended for wilderness deployment.

  • Seeed Xiao nRF52840 board with Wio-SX1262 radio (bottom center)
  • 3x INR18650-35E cells
  • No-name BMS strip (between cell holders)
  • Cheap "10W" (3W in reality) 6V solar panel (right, will be mounted to the box)
  • CN3791-based solar charger board (top)
  • DS3231 I²C RTC clock board (bottom left)
  • AHT20+BMP280 I²C sensor board (top center in the holder)
  • Cheap but decent 868MHz Gizont whip antenna (left)

Temporarily: a RAK PCB antenna for testing. I managed to destroy the uFL PCB connector on one of these units while disconnecting a pigtail before, not risking it again until I mount the pieces :D

Currently waiting for an oring strip and UV solder mask (PCB protection) to arrive. I'll also paint the box with an acrylic lacquer to give it more UV protection.
