Hello.
What I want to do is to ask to a pcb maker to create the BBQ20_USB_Keyboard for me (because it is sold out,but I need this nice keyboard for building my DIY phone)
The BBQ20_USB_Keyboard comes equipped with a blank RP2040 with nothing written to it.
I will need to write firmware to it.
It’s not difficult, though. The Raspberry Pi Pico RP2040 uses an excellent and simple method for writing firmware.
When I connect it to your PC via USB while holding down the BOOTSEL button, it will be recognised as a USB memory stick. All I have to do is place this file there.
However, there is a major challenge for me.
The BBQ20_USB_Keyboard board does not have a BOOTSEL button…
h t t p s : / / i b b . c o / H L S g L 3 R h
With a regular Raspberry Pi Pico, I simply press this button…
h t t p s : / / i b b . c o / n N 5 J 3 d c 7
With the BBQ20_USB_Keyboard l need to connect those two round metal terminals on the back of the board. But ZitaoTech (the creator of the keyboard) didn’t include that button.
If a tool like this one :
were narrower,it could work to electrically connect the BOOTSEL test metal terminal and the GND terminal while I connect the USB.
Someone can help me to find the narrower version of the alligator clip ? thanks.
