We have the new YJ-17076 USB UART Beacon in Stock. This beacon has been designed for IoT applications in that it includes a USB to UART chip and uses the NRF52832 that has lots of spare memory for use in more ambitious applications other than just advertising.
The CP2104 USB to UART chip allows you to create solutions that connect to other devices (desktop, laptop, single board computers) via USB to receive or send UART commands.
This beacon comes disassembled for ease of programming:
The Nordic NRF52832 chip can be re-programmed using Nordic tools and software to implement, for example, custom advertising schemes, custom Bluetooth services or Bluetooth mesh.
We have a selection of beacons that are powered from USB. However, up until now, very few of them have been controllable via USB.
We now stock the Minew U1 that has a CP2104 USB Serial converter that causes the device to show as a serial COM port device. This allows you to control it from other devices such as PCs, laptops, Linux or Android, as well as from the iOS/Android apps.
Why might you want to do this? Scenarios such as use with digital signage and video walls in shopping malls and stadiums sometimes need the beacon advertising to change in real-time as the display information changes. UART connected beacons allows the beacon advertising to be changed by the host device.
