Keyes ESP32-IO Expansion Board
The keyes ESP32-IO expansion board is compatible with the keyes ESP32 Core board (KE0162). It breaks out all the pins of the keyes ESP32 Core board with 2.54mm pitch pins. Two rows of pins with 2.54mm pitch supply DC 3.3V for external sensors and modules.
Simultaneously, keyes ESP32 Core board can by supplied power by inputting DC 7-12V voltage via DC head of shield. In addition, a DIP switch on the expansion board is used to control the power switch.
Power supply voltage: DC 7-12V
Working current: 60mA
Maximum power: 0.3W
Working temperature: -25℃ to +65℃
Environmental protection attribute: ROHS
Keyes ESP32 Core Development Board
Keyes ESP32 Core board is a mini development board designed based on ESP-WROOM-32 module. This development board leads out 2.54mm pitch headers from I/O to both sides. The users can connect peripheral devices on their needs. When using and debugging, the standard headers on both sides can make your operation more concise and convenient.
The ESP-WROOM-32 module is the leading WiFi + Bluetooth solution with less than 10 external components. It integrates antenna switches, RF balun, power amplifiers, low noise amplifiers, filters and power management modules. At the same time, it also adopts TSMC low-power 40nm technology. The cost-effective and radio frequency performance makes it safe and reliable to expand various applications.
