STD ESP8266 D1 Mini PRO Clone with 1S LiPo and RGB LED
License: MIT License
Mode: Schematic/Simulation
Cloned from ESP8266 D1 Mini Clone
[VERSION 3.5]
ESP8266 D1 Mini PRO Clone.
Analog RGB LED capable.
1 cell Li-Po powered.
Battery Powered:
The board is compatible with Li-Po and Li-Ion batteries.
Using the MCP73831T 1 cell battery charging circuit with charging led state.
There is also a proper load sharing circuit: Either the circuit is powered from the 5v USB or from the battery.
Board Power:
The board can be powered from the battery system.
It can also be powered by the USB power (5v)
Or it can be powered with the 5v input pin (MAX 6V)
The board uses a low noise LDO, the ME6211C33M5G-N, delivering 3.3v from the incoming power sources.
There is a small diode for protection at the 5v external input.
IO:
The board is fully compatible with the D1 mini pinout.
RF:
Customisable impedance with L1 and L2.
You can choose between two antena types, just solder the pad according to your need:
- SMD, good range and withing board outline.
- UFL connector, better for long range.
For the external antenna you can choose any 2.4ghz compatible antenna that has the UFL connector.
RGB LED:
Full Analog RGB led in SMD5050 package, with 220R resistor, you can change the value of the resistor in order to dim or brighten the color. You enable the direct GPIO used for the LED by soldering the pads on the bottom side of the board.
WIP : If you find anything wrong, please comment, the project can only be better with help.
