The SiPy is a MicroPython enabled WiFi, Bluetooth and Sigfox development board designed specifically for IoT applications. At its heart is the Espressif ESP32 System on Chip (SoC) featuring a dual-core microcontroller, WiFi, Bluetooth, Sigfox and 512 KB RAM. All this power packed into a board measuring just 55 x 20 x 3.5 mm!

Knowledge of Python on a PC or Mac transfers directly to working with MicroPython and SiPy so the learning curve is minimal. Pycom have developed an intuitive API to help you get the most out of your board.

NOTE: An external antenna is required for the SiPy and using without an antenna can damage the device. The Pycom Antenna Kit is recommended and available from RS 125-9535.

Two versions are available depending on your location:

SiPy RCZ1/RCZ3 Europe / Japan / Korea - RS 125-9533
