The FLipMouse is usually connected via a Micro-USB cable. In some cases, this might be unusable, see compatibility. The Bluetooth connection is not included in the normal construction kit, because this would add additional costs which is not always suitable. This page describes how to build the Bluetooth addon and which parts have to be bought.
- Buzzer (you can re-use the existing one)
- 4k7 (0.125W) resistor (you can re-use R3 for that)
- Adafruit Bluefruit EZ-KEY HID
- Female header 2x5 2.54mm
- Perfboard: 55x27mm
- Some thin wires
- Additional power source (eg. USB Powerbank)
- Unsolder the buzzer and R3 (only if you don't have a new one) on the main PCB
- Solder the female header as shown in picture 1
- Solder wires to following pins of the header (the upper left is pin 1, the lower left is pin 2 on the main PCB): 2 (VCC), 3 (buzzer), 7 (Teensy Serial3 RX), 8 (Teensy Serial3 TX), 10 (GND) Please use about 5cm wire for each pin and solder only ONE side
- Put the wires through holes in the perfboard nearby the soldered pin
- Solder the Bluetooth module, and connect following pins: "G" -> pin 10 (GND) "RX" -> pin 8 (Teensy TX) "TX" -> pin 7 (Teensy RX) "Vin" -> pin 2 (VCC)
- Solder the buzzer and the 4k7 resistor as shown in picture 2
- Connect one pin of the resistor to one pin of the buzzer
- Connect the remaining pin of the buzzer to GND
- Connect the remaining pin of the resistor to pin 3 (buzzer)
- Mount the addon board and re-assemble the FLipMouse (Picture 3 & 4)
No additional software is necessary. The FLipMouse firmware provides all necessary functions to provide a Bluetooth connection. The host device (PC, tablet, phone,...) does not need additional software, if Bluetooth is working.
The pair process of the addon is equal to the pairing process of the Bluefruit EZKEY-HID module. Press the pair button on the Bluetooth module for 5 seconds to start the pair process. If there is any prompt for a pairing password, please use 1234.
