USBLR110M is a low cost LoRa USB Dongle by SX127X RF modules as well as STM32 controller, both RFIC/MCU can be offered in different options.
LoRa is one of the most popular ISM IoT connectivities recently. However testing LoRa network/devices are quite expensive. Unless you can find LoRaWAN base station nearby, you can not design LoRa network with single board. In most cases, you have to buy a couple of boards to test PingPong and RxTx applications. And you have to invest more in pilot testing to evaluate your own MAC/NET/APP stacks as stress testing in field.
So we NEED a low cost LoRa board for prototype as well as pilot deployment. That's why I design USBLR110M with off-the-shelf STM32F103C8 mini board (aka. Blue pill). Since if I manufacture STM32 by myself, the cost is much higher than my purchase sources.
Compare to most of the competitive designs. USBLR110M has following features:
