GEEEKUS

If you're interested in making your project connect to the web and be part of the grander scheme of IOT (Internet of Things) then this board is the gadget for you! Like other microcontrollers and microprocessors, the ESP32 now has built in power regulation circuits, on board antennas and noise filters and fits snuggly onto a breadboard for rapid prototyping. The ESP32 can interface with other MCUs as master or slave or function completely standalone through SPI/SDIO, I2C and UART. The microcontroller can also support an SD card and multiple sensors .
The geeekus ESP32-WROOM-32 is a solid development board with original parts and yellow text on a black board, which makes identifying pinsets easier on the eyes.

The geeekus Mega 2560 R3 is a solid microcontroller board based on the ATMEGA2560-16AU, fully compatible with ARDUINO MEGA 2560 REV3.
It has 54 digital input/output pins (of which 15 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, 2 ICSP headers, and a reset button. The USB cable is also included. The geeekus MEGA 2560 has yellow text on a black board, which makes identifying pinsets easier on the eyes.
