This is a STM32WL based LoRa®/LoRaWAN® dev-board with all the necessary components for rapid prototyping.
Specs cont. (LoRa-E5 module):
Penguino power consumption (STM32WL in STOP2 mode w/ RTC enabled, @4.3 VBAT input):
*Power consumption can further be reduced by disabling the VBAT monitoring voltage dividers.
I needed a breakout board compatible with other Penguino boards so I can evaluate the LoRa-E5 module. At the time there was no dev-board available for it, but later Seeed guys came up with nice selection of dev-boards for this module.
Unlike the official dev-board from Seeed, this one is purpose designed to be low-power. It also provides better usability thanks to the wide selection of Feather compatible add-ons and expansion boards. Be sure to checkout the awesome-feather repo.
Since this was a low volume prototype run I only have 4 left. Default antenna path is routed to the SMA edge connector and the board doesn't come with an antenna. Please make sure you have a male 868/915MHz SMA antenna at hand.
