Hardware¶
The hardware used for development is the one proposed by F1ATB.fr .
On the photos bellow; as the heat dissipator provided by RobotDyn is under dimensionned, the triac has been unsoldered from the board and screwed into a big heat dissipator. Wires have been added to link the triac into the board.
A 12V power supply is used in addition with a buck converter to power the system. The 12V may be used to power a fan in an event of an over heating.
The router has been built to be connected to a frost protection system and then provide standard electricals sockets.
Using a regulator base on a triac¶
Bill of material:
- 1 x ESP32-dev board (Wroom-32U with external antenna)
- 1 x Green LED
- 1 x Yellow LED
- 1 x Triac from RobotDyn 24A
- 2 x resistor 470 Ohms for LEDs
Using a regulator base on a relay¶
Bill of material:
- 1 x ESP32-dev board (Wroom-32U with external antenna)
- 1 x Green LED
- 1 x Yellow LED
- 1 x Solid state relay
- 2 x resistor 470 Ohms for LEDs
The smallest Solar Router¶
Bill of material:
- 1 x ESP01 relay module board
- 1 x ESP8266 (or equivalent)
This router has some limitation
- It has to be used with ON/OFF engine and is not compatible with variable engine
- Due to the small space of memory, it doesn't support OTA update
