Question about TTL level compatibility, documentation, and identification of pinout area (LD2461 v1.3 CJ23A)

Question

Hello!

I have the following questions regarding the LD2461 v1.3 CJ23A radar module:

LD2461 v1.3

What TTL level compatibility is provided for the interface of this module? Is direct operation at 3.3V level possible, or is additional level shifting required when connecting to a microcontroller?
Where can I get the most up-to-date and complete technical documentation for the LD2461 v1.3 CJ23A, including connection diagrams, recommended operating conditions, and interface descriptions?
How can I find the pinout for the connector (area) marked with a red oval in the technical materials or device photos? If possible, please provide a schematic or description of this connector.

Thank you!

Best regards,
Aleksey Nekrasov

Hello Aleksey,
It’s great to hear from you, and thank you so much for your support.
Regarding your first question, we regret to inform you that this module does not support a 3.3V input. It specifically requires a 5V power supply to function properly.
For the relevant documentation, please refer to and review the following links:
