Introduction
The "PYBD Butterfly" board allows you to use your MicroPython Pyboard-D (PYBD) and its X-Y positions to facilitate rapid prototyping.
It also allows you to plug sensor and expansion board with popular connectors like:
- Qwiic (SparkFun) / StemmaQT (Adafruit)
- Grove (SeeedStudio)
- UEXT (Olimex) this Universal EXTension is robust ship I2C/SPI/UART and 3.3V/Ground power. A Must.
The Butterfly also offers more GROUND and Power connections. It uses male header for 3.3V points and female connector for GROUND points.
The Butterfly is distributed as a kit.

Assembly
Option 1: Solder the Pyboard-D on Butterfly
One of the options is to solder the PYBD on the Butterfly.
- The "advantage" is to have a very compacte assembly.
- The "inconvenient" is to definitively associate the PYBD with the Butterfly.
Solder the Pyboard-D on the Butterfly board. |
Option 2: Use female connectors
An other option is to solder the 1.27mm female connector on the Pyboard-D.
- The advantage is to allow you to remove the Pyboard-D from the Butterfly.
- The inconvenient of this assembly is to have a ticker solution.
