Particle Programmer Shield for Photon
The new and improved Programmer Shield is essentially a USB-JTAG converter that gives advanced users complete access to the Photon's memory space. It supports openOCD and the WICED SDK, and is built around the FT2232H high speed USB FIFO.
Pinout
- USB
USB connection that powers the programmer shield and exposes the FT2232H USB-JTAG plus USB-UART interfaces, per Particle legacy accessories documentation.
Type · power dataVoltage · USB powered; operating supply: USB - TX
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.
Type · serial - RX
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.
Type · serial - JTAG
FT2232H-backed JTAG programming/debug interface compatible with OpenOCD and Broadcom WICED IDE, per Particle documentation.
Type · debug - VIN
Photon shield header VIN rail exposed by the official programmer-shield Eagle schematic.
