Bees which do not have onboard programmable systems can only be configured by using the on-board FT232RL (USB to UART). These Bees are not suitable for standalone applications.
The on-board FT232RL can be used like any other 3.3V USB to UART interface when not connected to any Bee Modules. This is useful for programming a 3.3V MCU through the Serial Port.
Features
- Bee-compatible receptacle
- Two Grove connectors - one for I2C and one for D6, D5
- Two Grove placeholders
- On-board Charge Controller CN3063
- On-board 3.3V LDO Low-noise Micropower Regulator - RT9167A_33PB
- On-board FT232RL USB-UART IC
- LEDs for PWR, charge indication, and UART transmission.
- Power switch
- Reset button
- 2.0mm pitch JST connector for Battery and Charger.
Application Ideas
- Wireless Sensor Network with a standalone Bee Node like Wifi Bee.
- As a configuration aid for Bees using FT232RL.
- Charger for Lithium Ion Cells using the on-board charge controller.
- As an FT232RL-based 3.3V USB-UART interface.
