Tutorial / documentation

Communication

Quick documentation & first test preparation

  1. Identify component CH343G and its package.
  2. Identify the protocol, logic levels and each pin’s function.
  3. Check required termination and pull-up/pull-down resistors.
  4. Consult the application circuit in the linked documentation before testing.
