Features:

• The module is safe, reliable and scalable to various applications.


• The expansion board adopts a double-layer design, with a pin on both sides.


• Good stability and high reliability


• The breakout board can expand one GPI0 pin of the ESP32 board to two, great for you to reuse all the pins, a great ?tool for your project.


• Nice alternative to a breadboard to extend one GPIO pin of the ESP32 board to two. Great for users to reuse all pins in DIY projects.

B Specification:

• PCB material: high quality FR-4 material


• Number of PCB layers: 2 layers


• PCB thickness: 1.6mm


• Size: 7.8*6.3*1cm

A Specification:

The ESP32 integrates antenna switches, RF baluns, power amplifiers, LNAs, filters and power management modules, and the entire solution takes up minimal PCB area. 2.4 GHz Wi-Fi plus Bluetooth dual-mode chip

Adopting TSMC's low power 40nm technology, the power performance and RF performance are the best, safe and reliable, and easy to expand to various applications.

small volume. Easy to embed in any product.

Powerful, support LWIP protocol, freertos

Support AP, STA, AP+STA coexistence mode three modes

programming makes your development easier.

Note: The expansion board is only suitable for the 38PIN narrow version of ESP32 without mounting holes, not for the ESP-WROOM-32 DevKit V1 version. Please make sure your esp32 board pin width is the same as the expansion board pin width.
