Because some hardware setup is required to build up a functioning radio, an Arduino can be used to supply the voltage and control the radio chip. The 3.3-V power can be taken from the Arduino’s ...

So [Todd] has set out to build an Arduino frequency counter for a Kenwood TS-520S HF ham radio. This post (and the video found after the break) doesn’t cover the entire project.

It is compact, lightweight, and works great with any Arduino or Arduino compatible that supports Uno-style shields. The HamShield is the product of 12 months of design, engineering, and prototyping.

Measuring 68.5 x 50 x 10mm the eRA-ARDUINO-S900 Wireless Arduino Shield is powered by the host Arduino’s 5V, consuming 25/35mA in idle/transmit. An integral SMA antenna connector allows for use of an ...

It’s going to be incredibly exciting to see how the Arduino community reacts to it. We can only imagine what you guys can achieve with the extra features of the Nano RP2040 Connect board.” ...
