SuperB – An open, Bee-compatible ESP32

SuperB – An open, Bee-compatible ESP32

SuperB is an open source, Beecompatible 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.

  • Fully certified with integrated antenna and software stacks
  • One programmable LED

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.

The campaign is live on and has 25 days to go with plegdes starting at $23.
