COFDM Encoder module Advantage:
- Ultra-low latency H.265/H.264 audio thiab yees duab encoding ntau txhawb 1080P@60 real-time yees duab capture thiab encoding
- HDMI los yog AV audio thiab yees duab input, tom qab encoding, Ethernet chaw nres nkoj tso zis los yog tso zis rau wireless module, Yees duab encoding tom tus nqi yuav dynamically configured
- Txhawb audio input thiab audio decoding tso zis
- Txhawb ob yeeb yaj duab (HDMI+AV) ib txhij twg encoding (xaiv, Tus neeg ntawd yog HDMI los yog AV encoding, de ib tug ntawm ob input sourcing). )
- Web UI los sis serial chaw nres nkoj UART NTAWM command configuration tswj

FAQs
- Question1: Could you please tell me part number of this component, we try to find localy and check. Teb 1: It is a inductance named LOH32PN2R2NNC.
- Suggest Check Points: If the power supply current of the board is well but there is no RF output, maybe the below component TC1-1-13MX+ is generally damaged.
- In order to avoid damage to this device during transportation (the device itself is relatively high), Peb txiav txim liab glue tiv thaiv rau no ntaus ntawv thaum peb shipped nws.
- Tus engineer kuj qhia tias koj xyuas seb tus cable yog xoob los yog tsis nyob rau hauv kev txom nyem.
- Thov sim hloov tus FPC cable connecting ob boards
- We can provide spare parts if you're sure which one.

3. Lus nug, If our camera quality is good enough for both 4 MHz thiab 8 MHz bandwidth. Qhov no, Should the customer choose 4 MHz los 8 MHz?
Teb: Our one-way COFDM shipments use 4Mz wireless bandwidth by default, corresponding to a video bit rate of 3.12Mbps, which is enough for 1080p; If changed to 8MHz wireless bandwidth under the same conditions, the video bit rate doubles to 6.24Mbps. All customers can choose between wireless bandwidth 4MHz and 8MHz, even 6MHz can also be considered.
4. Lus nug: Which is better for this tx+rx set from a receive sensitivity view?
Teb: For wireless links, it can be simply considered that the receiving sensitivity will be higher at lower wireless bandwidths. From the perspective of receiving sensitivity, 4MHz>6MHz>8MHz

COFDM Relay Repeater module rau drone UAV wireless yees duab transmitter thiab receiver Vcan1870
Ib zaug xwb channel tau txais sensitivity:
-97+/-1dbm Ntawm QPSK 8MHz,
-98+/-1dbm Ntawm QPSK 6MHZ,
Sensitivity ntau zog los ntawm 3dbm thaum tau txais dual antennas
Yog, kev them nyiaj.
COFDM yees duab encoder modulator transmitter module 3.5G thiab 4G kuaj ntawd.
Tus receiver default firmware txhawb RTSP neeg uas ua ntawv, Ib txhia neeg xav UDP neeg uas ua ntawv, Peb kuj yuav muaj kev pab, then RTSP player doesn't support. (RTSP thiab UDP yuav tsuas xaiv ib qhov ob firmware)
