GPIO
The Electrum 100 has 23 GPIO available on connector J2 and is brought to the PRO050 boards J2 connector through a stacking header. P2 is an exact copy of the J2 connector and should be used to make prototyping connections. The Electrum 100 has an additional 24 GPIO available on connector J14 and is brought to the PRO050 boards J14 connector. P14 is an exact copy of the J14 connector and should be used to make prototyping connections. Below is the pin-out for P2 and P14 in regards to the Electrum 100.
Power
The PRO050 board has a ground bus (J4) and a VCC bus (J5) available to easily connect to ground and 3.3VDC. The Electrum 100 switching regulator is capable of providing 500 mA of current. The Electrum 100 has a typical current requirement of 250 to 300 mA. Due to the ground bus and VCC bus being supplied by J2 the J2 connection to the Electrum 100 must be made in order to use J4 and J5 for prototyping.
ADC
The Electrum 100 optionally has 8-channels of 12-bit ADC. To make it easier to prototype an analog front end the ADC available on the Electrum 100s J7 connector is brought to the PRO050 boards J7 connector through a stacking header. P7 is an exact copy of the J7 connector and should be used to make prototyping connections. Below is the pin-out for P7 in regards to the Electrum 100.
DAC
The Electrum 100 optionally has 4-channels of 12-bit DAC. To make it easier to prototype an analog backend the DAC available on the Electrum 100s J8 connector is brought to the PRO050 boards J8 connector through a stacking header. P8 is an exact copy of the J8 connector and should be used to make prototyping connections. Below is the pin-out for P8 in regards to the Electrum 100.
