For anyone interested in this, the system has undergone a significant change to simplify the assembly and servicing.
The new boards only have a power connection and the leads to the igniters. All of the previous cables have been eliminated. The circuit breaker is now on the board and will automatically reset when the over-current is cleared. The power to the board is reduced to a very low current level when the device is not selected so you no longer have to mess with a "SAFETY" switch. The display is mounted directly to the PCB. The 5v regulator which was previously an external device is also mounted to the PCB as is the LoRa radio. One addition is a coin battery for an optional real-time clock. This will allow time stamps for diagnostic messages
