# Chips and protocols

> Adsum works on any board built with a chip it supports: Nordic nRF52, nRF53, nRF54L and nRF91, and Espressif ESP32. There is no list your board has to be on.

Adsum works on **any board built with a chip it supports**. Your own design, a reference board, a development kit, or a product you bought off the shelf.

<Note>
  **The chip is what matters, not the board.** There is no list your board has to be on. Open your project and the agent reads it: your devicetree, your Kconfig, your build settings, and the hardware you have connected.
</Note>

## Nordic

Built with the nRF Connect SDK and Zephyr.

| Family | Parts                        | Protocols                          |
| :----- | :--------------------------- | :--------------------------------- |
| nRF52  | nRF52840, nRF52833, nRF52832 | Bluetooth LE                       |
| nRF53  | nRF5340                      | Bluetooth LE                       |
| nRF54  | nRF54L15, nRF54LM20          | Bluetooth LE                       |
| nRF91  | nRF9160, nRF9161, nRF9151    | NB-IoT, LTE-M, GNSS, DECT NR+, NTN |

Two device tools come with the cellular parts: a **board shell** that sends AT and Zephyr shell commands and reads until the board finishes answering, and a **modem trace** that decodes why a modem will not attach, including whether it found cells and never joined or saw nothing at all.

<Warning>
  DECT NR+ and NTN knowledge ships for both. NTN's modem firmware is a public download, but it runs only on an nRF9151 of the LACA A1A revision, not on LACA A0A, the nRF9161, the nRF9131 or the nRF9160. DECT NR+ needs a modem image from Nordic sales rather than a download.
</Warning>

## Espressif

Built with ESP-IDF.

| Family | Parts                                                                   | Protocols           |
| :----- | :---------------------------------------------------------------------- | :------------------ |
| ESP32  | ESP32, ESP32-S3, ESP32-C6, ESP32-C3, and the rest of the shipping range | Wi-Fi, Bluetooth LE |

## What we are adding

More chips and more radio technology. That work happens at the chip level, because every board built on those chips inherits it: nRF7x Wi-Fi, on-device AI on nRF54 and ESP32, LoRa, and Linux hosts with cellular hats. See the [roadmap](/platforms-and-roadmap).

If a chip you use is missing, tell us. That is the most useful thing you can send.

## Some devices go further

On a few boards the work is already done: pinouts, which card carries which radio, which connector programs which chip, written down and tested. Those are boards whose makers publish their designs and work with us.
