The BLE Mcicro is a low cost ARM cortex-m0 based module for Bluetooth® Smart designs with the nRF51822 SoC. The module gives access to at most 23 GPIO pins via pin pads and incorporates an on board PCB antenna to minimize material cost but also with a good performance.The application engineers can easily apply the module for theirs application without worrying about the specific impedance matching or soldering fine pitch related radio designing issues.

Help us make it better
Thank you for choosing Seeed. A couple of months ago we initiated a project to improve our documentation system. What you are looking at now is the first edition of the new documentation system. Comparing to the old one, here is the progresses that we made:
- Replaced the old documentation system with a new one that was developed from Mkdocs, a more widely used and cooler tool to develop documentation system.
- Integrated the documentation system with our official website, now you can go to Bazaar and other section like Forum and Community more conveniently.
- Reviewed and rewrote documents for hundreds of products for the system’s first edition, and will continue migrate documents from old wiki to the new one.
An easy-to-use instruction is as important as the product itself. We are expecting this new system will improve your experience when using Seeed’s products. However since this is the first edition, there are still many things need to improve, if you have any suggestions or findings, you are most welcome to submit the amended version as our contributor or give us suggestions in the survey below, Please don’t forget to leave your email address so that we can reply.
