Description
IMPORTANT. You will need to solder this yourself since you need preprogrammed chips! Furthermore, the footprint of the PIC24 is off so you will need to bend the legs a tiny bit to ensure they are a better fit. Also put some tape or isolating material between the communication board and the board this ensure it wont short out the USB You can buy the USB host here make sure you choose Keyboard [https://www.hobbytronics.co.uk/usb-host-ssop?search=usbhost](https://www.hobbytronics.co.uk/usb-host-ssop?search=usbhost)
