Outline:

FRS-DEMO-B is designed for walkie talkie transceiver module SR-FRS-1W and SR_FRS_0W5 demonstration, it can be used for both UHF（400M-480M）and VHF (136M-174M). It also can be used for voice intercom and data transfer demonstration. It is easy to set all the module parameter via the USB interface. When select the channel, it would voice broadcast the current channel number. You may quickly evaluate our module performance by the demo board, just make a little modify, it can be directly applied into your real production.

The demo board performance：

• The power switch, volume adjust, channel selection switch 3 in 1
• 16 channels can be selected by the encoder switch
• It is easy to switch the VOX (sound control transmit) by a VOX switch, the VOX level can be set via the PC
• Voice broadcast for the channel number, Chinese/English could be selected
