Deenlai FSH710

This enclosure is rather small, thus fewer Meshtastic boards are able to fit inside. So far, I have only tested the Heltec WiFi LoRa 32, which is one of the smaller boards available.

  • Internal Dimensions: 46 mm × 34 mm × 25mm

Heltec WiFi LoRa 32(V3)

:!: Double check the polarity and voltage of all wiring, the Heltec board will be damaged above 6 V or by any reverse polarity supply.

Tools Required

  • Philips #1 or #2 screwdriver
  • Soldering tools
  • Flush cutters or a good scissors

Extra Components Required


  1. Remove nut and washers from U.FL to SMA pigtail
  2. Insert U.FL to SMA pigtail into SMA Jack Adapter and install and tighten the nut and washer
  3. Unscrew nut and remove one of the cable glands from the FSH710 Junction Box
  4. Re-using the gland nut and rubber O-ring, install the SMA Jack Adapter into the FSH710 Junction box
  5. Route the external power wire into the remaining cable gland, optionally tying a knot to prevent pull-out through the gland
  6. Solder the exterma power wire to the input of the DC-DC converter
  7. Power up the buck converter and double check the output voltage, then disconnect from power
  8. Mount the Heltec board, then measure and cut the wire length required from the 3V3 or 5V pin to the DC-DC converter output
  9. Solder the output of the DC-DC converter to the Heltec board (outside the enclosure, where access is easier) and trim all excess wire length behind the pads off
  10. Connect U.FL to SMA pigtail to the Heltec board
  11. Place mounting tape on the DC-DC converter
  12. Mount the Heltec board and DC-DC converter into the enclosure
  13. Power up and verify Meshtastic boots
  14. Ensure all wiring is within the internal cavity of the junction box and will not get crushed by the case cover
  15. Install the cover of the FSH710 Junction Box and tighten screws
