Powering a 1.2v external circuit board

[echilon]

I have a solar powered novelty baloon which has a small solar panel, a 1.2V battery and a small circuit board. I'd like to bypass the solar
panel and just power the external board with 1.2(ish) volts. I've been so far unsuccessful in either powering the circuit board or measuring anything more than 0.03v across Pin32 and 3v3 with the following esphome config:

Code: Select all

light:
  - platform: monochromatic
    output: Pin32
    name: Pin32

output:
  - platform: ledc
    pin: GPIO32 
    id: Pin32

Am I missing something?
