FM/AM Radio

FM/AM Radio turns your Attaky into a full-band radio receiver. Tune in to FM and AM stations, scan the band, and listen through the device — a real radio in your pocket.

This firmware supports all Radio Series Complete Builds.

What you can do with it

Receive FM and AM broadcast stations
Tune by frequency or scan for stations
Listen on the go with the battery module

What you need

Already have a Radio Series build? It's ready to flash — FM/AM Radio runs on all of them.

Radio Pocket 1.0

Pocket-form radio receiver.

Radio Station 1.0

Desktop radio receiver.

Install it

Firmware is installed from the Attaky Firmware Store with a one-click web flasher — no toolchain to set up.

Open the Attaky Firmware Store in a supported browser (Chrome or Edge) and connect your Attaky over USB-C.

Pick FM/AM Radio and click flash. Keep the device connected until it finishes.

The device reboots into the radio. Tune to a station and listen.

Don't unplug while flashing. Make sure you pick the firmware that matches your hardware — FM/AM Radio needs the FM/AM Radio module.

Flash manually (advanced)

Prefer the command line? The release ships standard ESP32-S3 images:

File	Role	Flash address
`bootloader.bin`	Bootloader	`0x0`
`partitions.bin`	Partition table	`0x8000`
`boot-app0.bin`	OTA boot stub	`0xe000`
`firmware.bin`	Application	`0x10000`

esptool.py --chip esp32s3 write_flash \
  0x0     bootloader.bin \
  0x8000  partitions.bin \
  0xe000  boot-app0.bin \
  0x10000 firmware.bin

Addresses are the ESP32-S3 defaults and may vary with a custom partition table.

First steps

Power on, tune to a frequency, and listen. Reception depends on the antenna — extend it fully, and see the FM/AM Radio module page for details.

Upstream & license

FM/AM Radio is an open-source project that Attaky ports to its modular hardware and makes available to flash.

Known limitations

The upstream project grew out of the amateur-radio community, so some on-screen wording carries radio-enthusiast terminology. Run into something that doesn't work? See Troubleshooting & FAQ.
