One grouped connection is listed in the table but omitted from the graphic until individual pins are available.
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.
Photon shield header 3.3 V rail exposed by the official programmer-shield Eagle schematic.
Photon shield header ground pins exposed by the official programmer-shield Eagle schematic.
Photon digital header pins exposed/broken out on the programmer shield; Particle documentation says unused pins are clearly marked and broken out into header holes, and the official schematic exposes D0 through D7.
