Page 8: Operating Frequency
U-NII-3 (5725-5850 MHz) can be used as an alternative option. 7.2. Pinout Please note that the pinout listed here is seen from the VTX-301 side. For designing a system board interface, the input and output direction must be reversed. Typical internal PU/PD resistor is 30K-70K Ω. - Page 9 CAN Interface, Transmit output CAN1_TX VDD_3.3V (CAN FD/CAN2.0B) CAN0_RX CAN Interface, Receive input (CAN2.0B) VDD_3.3V CAN0_TX CAN Interface, Transmit output (CAN2.0B) VDD_3.3V 9/11 A printed version of this document is an uncontrolled copy © 2020 Unex Technology Corporation – Company Confidential...

Page 11: Thermal Solution
Applying a soft silicone thermally conductive pad to fill the air gap between VTX-301 and its system board could help disperse heat generated by the VTX-301 to the system board. It is recommended to keep continuous large copper pour area on the system PCB underneath the VTX-301, better with exposed bare copper especially directly under the CPU.
