Other key parts include the LD1117S33CTR and ESP-07. By type, the board carries 7 resistors, 2 ICs, 2 connectors, 2 capacitors and 1 transistor.

It belongs with the iot & wireless designs in this gallery.

From the project

P1 Port Thingie

It can be programmed with esphome using a 3.3V ftdi cable or similar. External power via rj12 is probably needed as the ftdi cables usually do not have enough power on 3.3V Installation guide and software: https://github.com/psvanstrom/esphome-p1reader.

Edit the p1reader.yaml and set board: esp01_1m

There is sometimes interference on the RX line when programming so it's preferable to program before adding the transistor.
