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.
Schematic
Assembly
Option 1: Solder the Pyboard-D on 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
Souder la Pyboard-D sur la carte Butterfly. |
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)
