Description
HT-M01 is a picocell LoRa gateway based SX1308 baseband chip, it’s must work with other operating systems (Windows® or Linux), when we designed it, we define this product positioning is convenient user authentication LoRa communication scheme. HT-M01 support both SPI and USB interface can work with Windows® (7, 8, 10 or higher) or Linux (Raspberry Pi®). With well-designed structure, the great heat from SX1308 can be transfer to the Aluminum shell, makes HT-M01 works more stable than other products of the same type.
Overview
