Summary of SuperB – An open, Bee-compatible ESP32
SuperB is an open-source, XBee-compatible ESP32 module designed to add Wi-Fi and Bluetooth connectivity to projects. Originally built for the Macchina M2 OBD2 scanner, it combines the popular ESP32 SoC with the versatile Bee form factor. This module supports multiple protocols including UART, SPI, and GPIOs, features a dual-core processor, and allows for OTA flashing using tools like the Arduino IDE.
Parts used in the SuperB Project:
- ESP32 System on Chip (SoC)
- Xbee form-factor compatible housing
- Integrated antenna
- 4 MB flash memory
- Programmable LED
- Headers for 3.3 V levels, UART, SPI, and GPIOs
SuperB is an open source, Bee–compatible ESP32 module for quickly and easily adding Wi-Fi and Bluetooth to your project. It combines the popularity of ESP32 with the XBee form factor to achieve an easy way of adding wireless connection to your board. It was originally build for use with Macchina M2 ODB2 scanner, check details below.
SuperB marries two of hardware’s ubiquitous names – the “Bee” form factor and ESP32. The Bee form factor was derived from DIGI’s XBee industrial grade IoT boards. This form factor has long been used to add wireless connectivity to hardware across the board. But in the maturing market of connected items, two protocols stand as required: Wi-Fi and Bluetooth. ESP32 brings both, and in an easy-to-use package – giving maximum flexibility to your existing hardware and for your next generation of modular, extensible products.

Macchina M2
SuperB was originally designed for use with another Macchina product – the M2, which is the open source OBD2 connector and dev board for car hacking. SuperB was designed based on feedback from the car hacking community, but motivated by our desire to avoid tripping over so many wires ourselves. M2 is also available for purchase during this campaign, so you can get the complete kit. It’s great for vehicle tuning, diagnostics, total customization, security, telematics, or prototyping, and works with just about any car manufactured after 1996.
