| Carrier to analog board | - How are we going to prevent ePixHRM carriers to be connected in to the 100kfps digital board and vice-versa?
- Options could be mechanical pins or change connector polarities
- Or via serial ID (needs to have a database) via soft locks
- Routes all power, data and control signals to/from the ASICs

| Analog to digital board | - Distributes the 24V from the power connector
- Routes data and control signals between the ASIC on the carrier and the FPGA on the digital board

| External power supply | - Should be on the bottom board (digital) because a pigtail is connected to it that is attached to the outside shell
- If if was on the top board (analog) there's a risk of damaging the ASICs and their wirebonds on the carrier
|
|
| Optical transceiver | - Same as for the power connector
- Place close to FPGA due to 25 Gbit/s signals
