$6.5 RAK11160 LoRaWAN, WiFi, and BLE module pairs ESP32-C2 with STM32WLE5 for low-power, long-range IoT

RAK11160 ESP32-C2 STM32WL LoRaWAN module

RAKwireless RAK11160 is a new low-cost, low-power LoRaWAN, WiFi 4, and Bluetooth LE module based on ESP32-C2 (ESP8684) wireless microcontroller and STM32WLE5 LoRa SoC for LPWAN IoT applications. The company noticed that many people would combine their STMicro STM32WL-based RAK3172 WisDuo LoRaWAN module with an ESP32 module to add WiFi and/or Bluetooth connectivity to their projects besides LoRaWAN. So RAKwireless decided to offer a module combining both STM32WL and ESP32-C2 to offer a cheap and much more compact solution to their customers. RAK1160 was born.
