Wireless Audio Transceiver Module - 770102 Users Manual Figure 1 RF Performance and Antenna configuration Outdoor range 30m. Maximum Transmitting RF Power - 15 dBm. Receiving Sensitivity -78 dBm. Frequency ISM 2.404 - 2.475 GHz. Operation mode – Adaptive FHSS. Antenna – PCB “F” configuration. Physical Dimensions L x W x H = 2.125 x 1.055 x 0.200 [in] SMT solder pads size (L x W) = 0.125 x 0.065 [in] Lead spacing (LS) = 0.100 [in] Electrical Parameters Absolute maximum Supply Voltage Range 2.3 - 3.6 VDC Nominal Supply voltage – 3.3VDC Current Requirements - 200mA Operating Temperature Range - 0 to 70 °C / 32 to 158 °F User Interface GPIO 6 GPIO connections are provided (with programmable / alternate functionality). These GPIO can take 0..3.3V voltage range and +/-6mA of current. Voltage exceeding these limits can result in damage to the module circuitry. Interrupt Capability is available on all pins. PCB Material and layout considerations The PCB material for the base PCB should be FR4 glass epoxy. FCC ID: WUO-770102 IC: 7985A-770102 Page 3 of 4 SONAVOX Inc. Wireless Audio Transceiver Module - 770102 Users Manual All supply pins should have decoupling electrolytic capacitors and ferrite beads positioned as close to the supply pins as possible. All digital audio pins must have small resistors (10..20 Ohms) or ferrite beads in series and positioned close to the module. No components or traces should be located close to the antenna. Recommended minimum distance is 1sm. Communications External devices can communicate with and through the module using low speed serial interface such as single wire communications (such as Infra Red Remote Control protocol) or systems using multiple connections (such as I2C, UART, SPI). Audio devices (ADC, DAC) have dedicated high speed digital audio serial bus that can be configured as (Left Justified, I2S or Right Justified). The configuration can be up to 24bit audio data with sampling rates of up to 48kHz. Audio Latency is selectable from 6ms to 25.1ms Addressing Several systems can work in close proximity when they have different address. The address is randomly generated during paring mode. The pairing mode is typically started using an external, user accessible switch connected to one of the GPIO pins of the module. Firmware Sonavox can provide customized firmware on the module for our customers. Other features The module is RoHS compliant. The module is FCC approved (documentation available on request). The module is IC approved (documentation available on request).
