bsfrance.fr site no longer available
The web site of BSFrance is not available for many months already (shows ‘502 bad gateway’ error). It looks like the shop may no longer be in (online) business.
BFrance designed the BSFrance LoRa32u4 (ATmega32u4) and LoRaM3-D (STM32) LoRa boards. The boards are produced by DIYmall which still sells the BSFrance LoRa32u4 boards.
