The Seeed nRF51822 Module 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 onboard PCB antenna to minimize the material cost but also with a good performance. The application engineers can easily apply the module for their application without worrying about specific impedance matching or soldering fine pitch-related radio designing issues.
