TS-7250-V3 MikroBus Header

The Mikrobus header is a 0.1" pitch 2x8 header which supports the Mikroe Click board ecosystem. This header features 3.3 V, 5 V, SPI, GPIO, ADC, PWM, a UART, and PWM. All I/O on this header are FPGA 3.3-V LVTTL.

The Click boards™ standard (where Click boards™ are a modular prototyping add-on board) is openly documented, allowing for custom boards to be designed.

By default all of these headers default to their non-gpio functions. These can be changed in the FPGA syscon register 0x08. For example:

# Make all mikrobus header pins GPIO:
peekpoke 32 0x50004008 0xF0

# Set only SPI to GPIO:
peekpoke 32 0x50004008 0x10
