A simple custom PCB/circuit for a two-way radio project

The circuit board would have to mount on stand-offs in a steel enclosure along with a small FM transceiver. The circuit would need to contain

> Some simple switching using NPN transistors

> A couple of pots used for audio attenuation

> A few filtering caps,

> A header pin jumper to reverse one of the input polarity (from active high to low),

> Some indicator LEDs,

> A local speaker level control

> Voltage reduction circuit to reduce 14.8 volts DC down to about 7.5 to 8volts DC

> 1 RJ45 jack for external radio interface

> DC input jack

> External remote switch input to enable the unit on/off with an external switch using a ground connection.

BNC antenna connection and DC input may be mounted in the enclosure and wired to the PCB board. This depends on the enclosure and layout of the components.

This would be a small volume project that I would like to have a small PCB board house produce in small quantities. I'm not clear on the procedure to have a PCB board fit into an enclosure. The PCB board would not likely fill the entire enclosure due to the transceiver taking up a good portion of the space.

Based on the description it seems you want to transmit/receive some data/audio over FM and then control something based on the data. This should be doable with the customizations you need. Also since you mentioned abou 更多
