A few questions here. I have trawled the community posts and wikis but can’t see any answers. Hope someone can help me before I try this for myself.
I have twelve circuits to measure and are using three emonTx v3 devices in an enclosure. All have a WiFI adapter plugged in on the programming header.
I have a 5V DC Power supply unit that I can use for powering the units with DC.
Can this PSU be connected to the block (using connector 1-5V and 3-GND) on each device rather than using a USB cable?
I also want to share the voltage reference so intend to use one 9V AC-AC supply and wire this in parallel to the three devices and plug into AI0 (9V input). Jumper JP2 is removed on all devices.
Aso want to check if the WiFi board can be connected directly to pinouts on circuit board as per EmonTx + WiFi Adapter purchase option, or does it require the Tx->Rx swap as per connection to programming header.
