Description
The module allows you to create a keyboard that communicates with your computer via Bluetooth, works with Mac, Windows, Linux, iOS, Android. It can be powered from 3 - 16 V, by default it allows access to arrow keys, enter, spaces and 'w', 'a', 's', 'd', '1', '2' characters with the possibility of programming any key through anFTDIconverter-details in the manual.
It is possible to combine several modules from Bluefruit series into one device. Each circuit has a unique identifier, all are CC & CE certified and comply with RoHS directive.
|
The module works with Bluetooth version 2.1 or higher. Please note that many cheap USB chips support the old version 2.1. In practice, all devices manufactured in the last 5 years should meet this requirement. |
Connection
The module has holes forgoldpin connectors- raster 2.54 (the strip is included). Below is a description of individual pins.
| Pin | Description |
|---|---|
| VIN | Supply voltage from 3 V to 16 V. |
| GND | The weight of the system. |
| RS | Reset. In order to restart the module, the low state - GND must be given. |
| PB | The output is connected to a button on the board and is used to reset the pairing of Bluefruit devices. If an external button is used, apply itto 3V, not to ground. |
| L1 | Signal output connected to the Key diode. Allows to lead the signal to an external indicator. |
| L2 | Signal output connected to the pairing diode. Allows you to output a signal to an external indicator. |
| TX | UART interface output pin. |
| RX | UART interface input pin. |
| 0 | Default arrow up. |
| 1 | Default arrow down. |
| 2 | Default left arrow. |
| 3 | Default right arrow. |
| 4 | Enter by default. |
| 5 | Default space. |
| 6 | The default is '1'. |
| 7 | The default is '2'. |
| 8 | The default is 'w'. |
| 9 | The default is 'a'. |
| 10 | By default, the 's' key. |
| 11 | The default is 'd'. |
In Windows with Bluetooth, the module will be detected and installed automatically, installation details for Linux(Raspberry Pi) MacOS can be found inAdafruit.
