particle.io Arduino compatible shield for the Nordicsemi nRF5x DK boards

2 layer board of 3.01x2.11 inches (76.35x53.47 mm).

This is a shield to mount the Particle.io (formerly spark.io) boards i.e. Core/Photon and Electron, on the nRF5x DK BTLE (Bluetooth) boards. This shield supports the nRF51-DK and the nRF52-DK boards.

Actions

When using the nRF51-DK, the shield requires that the solder bridge SB17 be bridged.

The P1 header on the shield needs to be in either reset position so a jumper is required. The “common reset” position ties the reset lines of the particle.io board and the nRF. This position does not allow the nRF to be flashed. The “reset/Program” position ties the D2 of the particle.io board to the Reset of the nRF. This position allows the nRF to be flashed.

See the particle.io website and the Nordic Semiconductor website for details of the boards used.

Parts required by the shield

1. Shield stacking headers
2. Headers for the Particle module
3. Header for Reset Selection. (Can use a solder line to do the selection)
4. Jumper for the Reset Selection. (Not needed if you used a solder line)
5. 18K Resistor for nRF_RESET pullup (optional)

Issues

1. The Central ICSP header is not required and was not used during testing.
2. Not tested with the nRF52-DK board
