Trident MCU Sandbox

This board is a combined version of Arduino Nano, ESP32 32E, Raspberry Pi Pico micro-controllers.Also has a battery holder and a battery protection plus charging circuit. Although you can charge it through a Mobile Charger BUT it is generally recomended to charge it through a Laptop. This board also features an adjustable Micro SD card slot, means you can connect the Micro SD card to any of these micro controller through jumper wires. Also have three OLEDs 1 for each mirocontroller. Have seperate USB-C connectors for each microcontrollers and charging the battery. Have in total five Buttons 1 for Arduino RESET, 2 for ESP RESET and BOOT, 2 for Pi Pico RESET and BOOTSEL. Have three NeoPixel LED connected to ATmega's PD4. To power or ON the whole board Short the two male pin headers mentioned 'Board' with the help of Jumper Caps. To power the different systems like the Arduino, ESP32, RP2040, OLEDs and Micro SD Card Slot short the pin headers labeled AT for Arduino systems, ESP for ESP32 systems, RP or Pi Pico systems and Micro SD for the Micro SD Card Slot. The GPIO or Other usable male pin headers are also labeled and also mentioned, A stands for Arduino, E stands for ESP32, R stands for Pi Pico. There are two Male Header Pins 1x2 labeled for 3V3 and GND, 5V and GND.
