Icom Ci V — Usb Interface Schematic Top [exclusive]

If you are building one from scratch today, is highly recommended.

This was the standard design in the 1990s and 2000s. It converts USB to RS-232 voltages (+/- 12V), and then converts that back down to TTL for the radio. icom ci v usb interface schematic top

: For those using a basic USB-to-TTL adapter, a simple circuit using two transistors can combine the TX and RX lines into the single-wire CI-V bus. If you are building one from scratch today,

: Most USB CI-V interfaces are powered directly from the computer's 5V USB bus, eliminating the need for an external power supply. : For those using a basic USB-to-TTL adapter,

Thus, on both the receive and transmit paths.

: If using a pre-made CP2102 or FT232RL breakout board, identify the Solder the Bridge

As technology advances, we can expect to see improvements and upgrades to the ICOM CI-V USB interface. Some potential developments include:
