LoRa module in DIL form

Monday, May 7th, 2018

Mare writes: Murata produces LoRa module CMWX1ZZABZ-xxx based on SX1276 transceiver and STM32L072CZ microcontroller. The soldering of the LGA module is not very hobby-friendly. I constructed small breakout PCB for this module with additional buck/boost switcher and place for SMA connector. The transceiver features the LoRa®long-range modem, providing ultra-long-range spread...

SQUIX ESP8266 based e-paper WiFi weather station

Friday, October 27th, 2017

Erich Styger documented his experience building Daniel Eichhorn’s e-paper weather station with a custom enclosure: Using e-paper for a weather station is an ideal solution, as the data does not need to be updated often. By default, the station reaches out every 20 minutes for new data over WiFi and...
