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).
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.
Schematic
Assembly
Option 1: Souder la Pyboard-D sur la Butterfly
Une des options est de souder directement la PYBD sur la Butterfly.
- L'avantage est que l'assemblage est très compacte.
- L'inconvénient c'est que la PYBD est "bloquée" sur la carte

Option 2: Utiliser des connecteurs femelles
Une autre options est de souder des connecteurs femelles 1.27mm sur la PYBD sur la Butterfly.
- L'avantage est qu'il est possible de retirer la Pyboard-D de la Butterfly.
- L'inconvénient c'est que l'ensemble Pyboard-D + Blutterfly est plus épais (massif)
