JTAG programming switch for Raspberry Pi 2+, Pi Zero….. Program your Raspberry Pi via JTAG (simple JTAG config program required for SD card: Put GPIO22-25,27 in ALT4 mode; GPIO4 in ALT5 mode). The JTAG loaded software can then reconfigure these for GPIO use (place switch to RUN mode).
Designed around standard 20 pin JTAG header - used successfully with Olimex ARM-USB-OCD-H.
Enables use of JTAG pins as GPIO when done programming via JTAG (Run<>Prog switch).
