DC low voltage heating table V1

Want to solder beautiful boards? Don’t you have to have tools first? Here are the patch tools (YYDS for Lichuang Aluminum Substrate)

DC version power supply: 12-24V DC power supply 3A-10A is available  

PD version power supply: PD fast charge>65W 

Update log: September 01, 2022

1. Repair the power control (fast charging overload protection when using a high-current heating plate, the device is repeatedly powered on and restarted)

2. Remove the mini fan socket and related components.

Update log: August 30, 2022

1. Added mini version to remove DC external power supply.

2. Minor firmware modifications.

3. Update PCB component parameters

Update log: August 15, 2022

1. Add Blinker, an IoT control function platform

2. Use Blinker APP to configure the key, and use the APP’s built-in esptouchV2 version mode for network configuration. 

3. Real-time display of IP, attitude, signal, temperature, voltage, PWM ratio

4. Remote control to turn on or off heating, temperature control, temperature setting, and sleep setting. Restart and wait...

Tip: Use esptouch or blinker app for network configuration. The default timeout for initial connection to WIFI is 45 seconds (can be turned off). If no wifi user information is received within 45 seconds, it will be skipped. If you need to connect again, just press the RST button.

2. Double-click to open the menu

3. Press and hold to exit the menu in menu mode (press and hold for 8 seconds to reset WIFI connection information)

4. Adjust the set temperature left and right in the menu

5. Parameter left and right adjustment is turned on or off  

hint:   

The first time burning program can be connected to the computer through the onboard type C to flash the firmware, and subsequent OTA updates can be used.

There are a lot of ESP flashing tutorials available. There are also tool accessories

Flashing software: flash_download_tool_v3.9.2.zip

Firmware: Heating stage firmware (version number).bin

Tip: All parameters have the function of saving when power is off. The heat insulation board can be cut off the display part from the excess PCB and placed on the copper pillar. The heat insulation cotton can be added to the middle layer to improve the heat preservation capability.

Other functions: voltage detection, dumping detection
