BMB81TB01A

The BMB81TB01A is an IoT expansion board developed by BestModules for the BMduino series, designed specifically for the BMduino UNO development board (BM53A367A) . Simply stack this expansion board on top of the main board and it immediately converts the scattered I/O pins into easy-to-use HY2.0 keyed connectors, greatly simplifying wiring and setup.

The board features a built-in Wi-Fi + BLE 5.0 wireless module and multiple 5-pin keyed connectors, allowing quick compatibility with a wide range of BMduino modules. Whether for classroom teaching, sensor integration, IoT learning projects, or interactive device development, the BMB81TB01A helps make your development workflow more intuitive, smoother, and easier to manage.

Product Description

The BMB81TB01A is an IoT expansion board created by BestModules for the Arduino ecosystem. It can be directly stacked onto the BMduino UNO (BM53A367A) . The BM53A367A fully supports Arduino UNO R3 pin mapping and development methods, while offering enhanced I/O capability and power stability, giving users more flexibility when developing hardware under the familiar Arduino IDE and commonly used libraries.

When paired with the BMB81TB01A, the UNO’s original digital pins, analog pins, and multiple serial interfaces are reorganized into clear and easy-to-read HY2.0 keyed connectors, reducing the time spent checking pinouts or dealing with jumper wires. This setup is ideal for teaching labs, prototyping, or projects with multiple sensors.

The BMB81TB01A covers a wide range of applications—from basic sensor learning and interactive design to full IoT projects—providing educators, makers, and developers with reliable expansion capability and a smooth development experience.
