Challenger RP2040 LoRa board combines Raspberry Pi RP2040 MCU with RFM95W LoRa module

Invector Labs is now offering a variant of the WiFi-based Challenger RP2040 board with a LoRa radio. The Challenger RP2040 LoRa board features the Hope RF RFM95W LoRa radio transceiver module instead of the ESP8285 WiFi chip found in the original board. Raspberry Pi RP2040 has already been used in combination with a LoRa module, notably in Rakwireless RAK11300 WisDuo LPWAN module and the “LoRa Expansion for Pico“, a baseboard for Raspberry Pi Pico equipped with a LoRa module, but it’s the first time I see the combination in a development board form factor, which as a potential bonus following Adafruit Feather form factor. Challenger RP2040 LoRa board preliminary specifications: MCU – Raspberry Pi RP2040 dual-core Cortex-M0+ MCU @ 133MHz with 264KB SRAM Storage – 8MB flash Wireless module – Hope RF RFM95W connected via SPI channel and some GPIOs 168 dB maximum link budget. +20 dBm – 100 mW […]

How to Make a Cheap Single Channel Gateway with an ESP32 LoRa Board

Actual LoRaWAN gateways based on Semtech SX1301 concentrator  can be pretty expensive,  and even if you take a LoRa gateway design based on Raspberry Pi for indoor placement or experimentation, price is still around $200. A much cheaper way (~$70)  is to use a single channel LoRa gateway, which as the name implies only support one channel, which limits the number of nodes, and forces you to set the nodes at the same frequency as your gateway. Those are not really suitable for commercial offerings, but if you manage your own gateway and nodes that should be usable. If you only plan to implement a network with a dozen nodes or so, you could even use much cheap ESP32 LoRa board like the ESP32 LoRa 1-Channel Gateway sold on Sparkfun for $29.95. Hardware specifications: Connectivity WiFi and Bluetooth 4.2 LE via ESP32-WROOM-32 module with integrated PCB antenna LoRa @ 868 […]
