This is a very flexible VIK module specifically designed to prototype various configurations. If you’d like to test out external breakout boards, including the use of an I/O expander, shift register, switches, leds, and more, this is the module to get! See the github link below for more details.
Everything is pre-soldered as shown in the product picture (not the fully assembled one, but the bare pcbs).
Note that this does require a VIK controller or keyboard connected to write firmware and test the module
Includes the PCB and a 10cm FPC cable
