The circuit and PCB have been produced and tested and basic code is available on github. See the project site on hackaday.io for more information about the project.
EPSOLAR VS6048 Charge Controller (CC) has a MODBUS port. Vital data is available for use M&E of the PV system to which the CC is attached.
A NodeMCU based EPSOLAR VS6048 CC Monitoring system is implemented using MAX485 to get data from two CCs attached to a 48 VDC battery system in our offgrid home.
# Wifi Modem ESP8266 - ESP-01 #
**for Retro Computer**
Simulates the old-style Hayes "AT" commands, so that the ESP8266 appears to the terminal as if it were a Hayes modem. These "AT" commands may then be issued to the ESP8266 in order to force it to connect to a wireless access point, and from there to make one or more manageable connections to the internet. It also includes...
This is a battery powered sensor board based on the ESP8266 (ESP-12F).
By using a TPL5111 chip the battery consumption can be reduced to about 1µA when the ESP is not enabled. When the TPL5111 chip receives 5V at it's wake up pin this will turn the ESP on by enabling the 3.3V voltage regulator. At this moment you can run any program you want. If you want to turn the ESP off again you have to drive...
Этот проект первоначально был предназначен для создания терморегулятора овощехранилища для лоджии на базе ESP8266 с универсальной прошивкой ESPEasy. https://www.letscontrolit.com/wiki/index.php/ESPEasy

NeoPixel led strip controller, designed especially for led suits. It can:
- display animation - sequences of frames at regular (given) interval,
- switch animations on MIDI event - note on/off, velocity used for brightness adjust,
- MIDI over UDP over WiFi (UDP broadcast so far, but i'm working on multicast),
- use regular SD card to storage animations.

2 relays WIFI commutation
just 1 strap for single face PCB
This board can be powered through differents kind of powers :
from the H1 connect a LIPO battery (deepsleep available shunt GPIO16 to RST pins)
from the H1 connector DC 3V3 directly (shunt in&out AMS1117 pins and use 3V3 relays)
from the H1 connector DC input from 5V to 15V (adapt the relays' voltage)
using a AC/DC power converter HLK-PM01...
