USB-JTAG converter shield for the Particle Photon built around the FT2232H high-speed USB FIFO. Provides full access to the Photon memory space; supports openOCD and the WICED SDK.
USB connection that powers the programmer shield and exposes the FT2232H USB-JTAG plus USB-UART interfaces, per Particle legacy accessories documentation.
Particle device Serial1 TX connection used by the FT2232H USB-UART interface; Particle documentation states the USB-UART interface is connected to TX and RX of a Particle device.
Particle device Serial1 RX connection used by the FT2232H USB-UART interface; Particle documentation states the USB-UART interface is connected to TX and RX of a Particle device.
FT2232H-backed JTAG programming/debug interface compatible with OpenOCD and Broadcom WICED IDE, per Particle documentation.
Photon shield header VIN rail exposed by the official programmer-shield Eagle schematic.
Shield
Confirm the data interface matches your host board.
Module pins: VIN, 3V3, GND, TX, RX. Schematik maps them to your board in the app.
About 270 add-ons across Pi HATs, Arduino shields, and FeatherWings. The same function — motor control, PoE, display — usually ships once per host connector family. Get the host board right first.
