Just want to knock a little board to connect to the E-100 and have an ESP-01 for the console & a HC-12 for Com1. Was just going to use the 40 way header & a fly lead for the console. The board would only have the 2 modules + a 1000uF & 0.1uF cap for each device. Just wondering if I'm also better off to add a separate 3.3V reg & one more 0.1uF cap to run the ESP off it's own reg instead of the E-100's 3.3v supply. Tiny extra effort if it's more stable. Thanks Phil. PS. Any issues if the two modules are just cm apart? |

The ESP is power hungry and power sensitive. I would go with a dedicated reg. Jim VK7JH MMedit |

I can confirm that I had to change the reg on the E100 board for a larger one for it to work properly all the time with the esp on my weather board |
