I need a JST SH 4-pin to JST PH 3-pin wires adapter to connect a Adafruit QT Py to an Adafruit MOSFET Driver. The QT Py has a JST SH 4-pin and the MOSFET Driver has a JST PH 3-pin socket.
Here are the parts I’m using.:
MOSFET DriverAdafruit QT Py ESP32-S3 WiFi Dev Board with STEMMA QT [8 MB Flash / No PSRAM] : ID 5426 : Adafruit Industries, Unique & fun DIY electronics and kits
Hello,
The only JST part I found was on the JST web site. STEMMA QT / Qwiic JST SH 4-pin to Premium Male Headers Cable - 150mm Long. Is what they show.
The Adafruit part number is 4209, DigiKey part number 1528-4209-ND
I do not see any type of 3 to 4 pin adapter from JST.
The connector on the Adafruit MOSFET Driver 5648 is meant only for V+, signal, and ground. The Adafruit board 5426 has a connector that is meant to be used with I2C. To send signal to the driver board you are going to need to use a different pin that is not SDA or SCL.
If you use an adapter cable, you would also be limited 3.3V and 600mA.
What solution do you recommend?
The connectors between the boards are not compatible. You will need to connect the MOSFET driver board to the pins on the ESP32-S3 board instead.
