− | + | Put some solder on the tip of the iron and put it on the pins. Thanks to the flux, the solder will automagically melt quickly on the pads. | |
− | + | '''Next''', just make a solder joint on the fixation pads on the front of the connector (near of the board edge). | |

− | + | Load the iron tip with some solder and drop off the solder on the connexion pin first (solder should easily melt down on the pads and the pins). | |

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 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
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)
