The mini::pit is based around the ESP32-WROOM-U, a WLAN 802.11 b/g/n and Bluetooth LE capable chip. It adds a second CAN bus with transciever, filter and ESD protection to the mini::base. Connect it to your custom application via the two Binder subminiatur connectors with wire out CAN, power supply and IOs.

the mini::pit features an Espressif ESP32-WROOM-32U microcontroller, thereby adding another full mcu to board stack. aside from bluetooth and wifi, this adds computational power, the ability to drive small touchscreens and a second CAN bus interface.

  • - Espressif ESP32-WROOM-32U with Xtensa┬«32-bit LX6 MCU
  • - … meaning basically another full MCU
  • - bluetooth low energy (BLE) capabilities
  • - Wi-Fi capabilities
ESP32-WROOM-32U details

with the mini::pit, we aimed to create a versatile extension to the mini::base for local wireless applications. in terms of the wired interface, there are two footprints for THT loom connectors which wire the power supply and one CAN on one and some I/Os and the other CAN on the other, it has a connector for a small display and it has a connector for an external BLE / WiFi antenna.

  • - loom connectors (by Binder, 4p and 5p)
  • - display connector by molex
  • - CAN identical config as on the mini::base

the size of the mini::base

size is not the most important aspect for a development-style board. nonetheless we aimed to keep it compact yet robust, again with the goal of making the board::project line viable for more than just desk environments. as a visual aid and to ease integration, we decided to use the credit card form factor as a reference, and the mini stack is exactly half a credit card in footprint at 54.0mm x 42.5mm.
