Wappsto:bit GO is an IoT board, similar to micro:bit, with an ESP32 and an on-board microcomputer. Wappsto:bit firmware brings the fun back to IoT projects. It works out of the box, and the included cloud access lets you take your projects online in minutes rather than spending your time setting up your own cloud. You can then use the Wappsto IoT platform to control your devices, view and analyze your data, build dashboards, and much more.

IoT Hardware That Won’t Just Collect Dust!

Wappsto:bit GO is the latest addition to the Wappsto:bit series. It includes an ESP32 and provides similar functionality to a micro:bit. Wappsto:bit GO features an edge connector, so it works with all breakout boards compatible with micro:bit.

Easy Sensor & Actuator Attachment

Simplicity, Versatility, and Extensibility

Program Using MakeCode

Wappsto:bit GO can be programmed with MakeCode. To easily communicate via I²C with the onboard ESP32, simply install the Wappsto Extension and the rest is standard MakeCode.

Analyze Sensor Data From the Dashboard

Wappsto:bit GO is fully integrated with the Wappsto platform. Once you’ve programmed your project in MakeCode, your device and data are immediately accessible on Wappsto, where you can configure your own Dashboard or extract your data for further analysis.

All you need is a Wappsto:bit and a free account on

Automate & Interconnect Devices!

With Wappsto Blocks you can build your own W(apps) that work with your Wappsto-connected devices. You can also find third-party integrations.

Write Your Own ESP32 Firmware!

Finally, you can use our Arduino examples to communicate with micro:bit and to make your own Wappsto integrations. (Or you can design your own project and features from scratch, of course.)

Support & Documentation

Manufacturing Plan

Wappsto:bit GO design and software are finished and awaiting campaign completion, at which time we will source components and begin manufacturing devices. Production is to be carried out by a trusted long-term partner with whom we have worked to manufacture thousands of IoT devices in the past. We will handle product testing and packaging ourselves.

Support & Logistics

After testing and packaging the production batch of Wappsto:bit products, we will send them on to Crowd Supply’s fulfillment partner, Mouser Electronics, who will distribute them to backers worldwide. You can learn more about Crowd Supply’s fulfillment service under Ordering, Paying, and Shipping in their guide.

Risks & Challenges

Our team in Denmark has delivered hundreds of thousands of high quality IoT devices worldwide. Due to the uncertainty inherent in the ongoing component shortage and global pandemic, however, our timeline could be delayed. To help mitigate this risk, we have already identified suppliers for all components as well as backup suppliers for non-single-source components.

In the Press

Geeky Gadgets

"If you are interested in building Internet of Things applications and projects, or a teaching IoT fundamentals to students, you may be interested in a new IoT development board soon to be launched via the Crowd Supply website."


"Episode 53 - This week’s maker news stories include NodeMCU ESP32-C3 boards released, an Arduino-powered Apollo guidance computer, and more DIY delights!"

CNX Software

"The new board is notably equipped with a wider range of sensors including a light sensor, a magnetometer, and sound sensor beside the temperature sensor and accelerometer present in the original board..."
