The SpiderR40ESP32C3 turns a radino40 radio module into a working device: USB-C, antenna connector, power supply and every pin of the module on solder pads — on 50.8 × 25.4 mm. An ESP32-C3 with WiFi and Bluetooth sits on the board as well, sharing a UART with the radino40.
The board ships with the radino40 already soldered on. Which module sits on it determines the radio technology — the board itself stays the same.
- Carrier for radino40 modules: CC1101, DW1000, DW3000
- ESP32-C3FH4 with 4 MB flash, WiFi and Bluetooth LE
- USB-C for power, programming and the serial connection
- RP-SMA antenna socket for the radino40
- Every pin of the radino40 on solder pads, 2.54 mm pitch
- Five free pins of the ESP32-C3 (IO0 to IO4)
- Powered from USB-C, 5 V or 24 V — the inputs are decoupled
- 3.3 V from a linear regulator, up to 600 mA
- Two buttons, three LEDs
- 50.8 × 25.4 mm, 12 g
The ESP32-C3
A firmware is supplied that runs it as a USB-to-UART bridge: the board appears on the computer as a serial port, and the radino40 can be addressed and programmed directly. The source comes as an Arduino sketch and serves as a starting point for your own firmware — the ESP32-C3 can equally handle the network connection while the radino40 runs the radio traffic.
The price shown is that of the board. Choose the radino40 above – it is soldered on and the board is tested before delivery; its price is added.
