This product is compatible with raspberry faction B + B motherboard and raspberry send motherboard. B + and B shall be inserted insertion method method compatible, B +'s GPIO 1 foot, the corresponding paragraph B GPIO1 pin on.
This is a 2.4GHz Wireless Complete Module. Wireless communication become extremely easy.
Auto-acknowledge and auto-retransmit abilities
Internal filtering results in high margins of meeting RF regulatory standards. The module's radio uses Gaussian Frequency-Shift Keying (GFSK) modulation as well as fast Automatic Gain Control (AGC).
The module includes an Interrupt Request (IRQ) pin which can be used to wake the host microcontroller, (ex: Arduino), from sleep when the module receives a transmission providing great power conservation in battery devices.
