ESP32-S2-WROVER is a powerful, generic Wi-Fi MCU module that integrates ESP32-S2. It has a PCB antenna, a 4 MB external SPI flash and an additional 2 MB PSRAM.
All available GPIO pins (except for the SPI bus for flash and PSRAM) are broken out to the pin headers on the board. Users can program ESP32-S2 chip to enable multiple functions such as SPI, I2S, UART, I2C, touch sensors, PWM etc.
A four digit UP counter module designed using CD4026 ICs which can be used to count from 0 to 9999. Count will increment in each LOW to HIGH pulses applied at the CLK input of counter module. Module can be used to count motion easily by connecting a PIR motion sensor directly to the module. No programming required.
