ESP32 38 Pin Breakout PCB Board with General Purpose Prototype PCB – Dual Width (2.4cm & 2.6cm) Universal Expansion Board for Beginners, Students & Makers (Only PCB)

The Blue Horizon BH-02 is an ESP32 38-pin breakout PCB that accepts both 2.4 cm and 2.6 cm wide modules, so one board covers the common sizes. It is a bare PCB, so you add your own ESP32 module. A large dot-matrix prototype area lets you solder sensors, regulators and other parts onto the same board.

Key Features

• Dual width: fits 2.4 cm and 2.6 cm 38-pin ESP32 modules
• Two solder pads per GPIO: a compact pad for experienced users and a wider, spaced pad for beginners
• Dot-matrix general-purpose prototype area in the lower half of the board
• Four corner mounting holes for enclosures and project boxes
• FR4 substrate with HASL finish

Compatibility

Works with 38-pin ESP32 modules such as ESP-WROOM-32, ESP-WROOM-32U, NodeMCU-32S and ESP32-DevKitC.

Specifications

• Board size: 4 x 12.3 cm
• Module widths: 2.4 cm and 2.6 cm
• Board material: FR4, HASL finish
• Included: PCB only (ESP32 module not included)

Ideal Uses

• WiFi sensor nodes
• Home automation controllers
• BLE beacon prototypes
• College electronics projects
• Arduino-to-ESP32 migration
• Robotics control boards
