This is a four port Songle 5V relay board, with an onboard 5V transformer and 3.3V LDO regulator, using ULN2003A for flybacks and to switch up 3.3V input signals to the relays. Best used with 2oz or more copper pours, is rated for 10Amps.
The power supply is 1A max, the relays pull ~300mA when they’re all on, leaving 700mA for the driving device.
