The ESS3H32 is an ESP32 S3 IoT expansion board developed and manufactured by eletechsup. It features 16 opto-isolated digital input ports and 16 MOSFET output ports with isolated surge protection. It can be used in smart home applications such as LED dimming and motor control.

Note: ESP32 S3 board is not included!!!
Please contact me for more detailed information.

Product Features:
1 Operating voltage: Wide voltage DC 7-30V
2 Operating Current : 60-80MA(ESP32 S3 standby power consumption)
3 16CH NPN Optoelectronic isolation input port(supports 3-24V level)
4 16CH NPN 3A MOS output(DC 3-30V),Support PWM control.
5 Configurable onboard LED/Buttons,Lead out the remaining IO ports
6 Size : 180*72*13mm(Only Board),193*83*19mm(With DIN Box)
7 Weight : 96g(Only Board), 222g(With DIN Box)

16-channel NPN 3A MOS output:
1. Optically isolated MOS control
2. With a freewheeling diode, the MOS can drive inductive loads
3. Supports PWM control for LED dimming (PWM cannot exceed 8 channels)
4. PWM frequency: 200-2000 Hz
5. MOS drive current: DC 3.3-4.5V <2A; DC 4.5-8V <4A; DC 8-30V <5A
6.The MOS model is 30N06. The output driver does not have overcurrent and overvoltage protection. If the MOS is burned out, please use a TO252 package 30N06 to replace it.

This is an expansion board based on 44PIN ESP32 S3. We only provide some Arduiuo codes for testing the hardware. More codes and functions need to be developed by yourself.
If you need more functionality, write your own code. We do not provide additional code and technical support

Note:
1 ESS3H32 can not work independently, must be under the control of the 44PIN ESP32 S3 board to work,If you do not have a 44PIN ESP32 S3 board, purchase it separately or purchase a kit with 44PIN ESP32 S3
2 Since the ESP32-S3 has only 8 general-purpose timers, a maximum of 8 PWM ports can be configured at a time.
3 When using the output port,The MV1+/MV1- MV2+/MV2- MV3+/MV3- MV4+/MV4- port should be connected to a power source (DC 5-30V)
