๐ Overview
ADSBee is an open-source embedded ADS-B receiver project that receives and decodes position signals (ADS-B) broadcast by aircraft themselves and delivers aircraft position, altitude, and identification information over a network.
ADS-B (Automatic Dependent SurveillanceโBroadcast) is an air surveillance technology in which aircraft periodically broadcast their GPS position, altitude, speed, and aircraft identification information via 1090 MHz radio signals without relying on radar. These signals can be received not only by ground control stations but also directly by drones, aircraft, and ground systems equipped with appropriate receivers, enabling applications such as air traffic monitoring, collision avoidance, and aviation data collection.
ADSBee decodes these ADS-B signals (primarily 1090 MHz) in real time using only the PIO (State Machine) of the RP2040 microcontroller, and transmits the decoded data to external systems via Ethernet/Wi-Fi networks based on the ESP32-S3 and WIZnet W5500.
As a result, ADSBee implements a compact, low-power, always-on, network-based ADS-B receiver that operates without a PC or SDR equipment, and provides an extensible architecture suitable for applications such as drone collision avoidance assistance, fixed aircraft reception nodes, and aviation data collection infrastructure.
๐ Background

Reference: https://pantsforbirds.com/wp-content/uploads/2024/10/datasheet_adsbee_1090.pdf
ADSBee 1090 is a project that was initiated to make complex and expensive conventional ADS-B receivers simpler and more affordable.
Traditional ADS-B receivers are either costly devices based on FPGAs or require external computing equipment such as SDRs and PCs, making installation and operation difficult. ADSBee 1090 was designed to address these limitations, with the goal of creating an embedded ADS-B receiver that operates without an FPGA or an external computer.
By leveraging the PIO feature of the RP2040 microcontroller, ADSBee 1090 performs real-time ADS-B signal preamble detection and decoding, while the other core is dedicated to aircraft information interpretation and data processing. The decoded aircraft data can be output directly via USB or UART, or transmitted over a Wi-Fi network through the onboard ESP32-S3, enabling aviation data streaming without the need for additional equipment.
๐ Development Process
The development process was updated on the blog almost every month.
December 2024 โ Support for connection with the W5500 Lite module
https://pantsforbirds.com/adsbee-1090-december-update/

In the December 2024 update, support was added to ADSBee 1090 for connecting the W5500 Lite Ethernet module.
This enabled network connectivity over wired LAN in addition to the existing Wi-Fiโbased data transmission method. At that stage, the Ethernet functionality was in an early phase and was primarily intended to validate practical applicability.
May 2025 โ Release of the ADSBee PoE pant
https://pantsforbirds.com/adsbee-1090-may-2025-update/

In May 2025, the ADSBee PoE Pant expansion board was released.
The PoE Pant is designed to provide both Ethernet connectivity and power supply through a single cable, allowing the device to operate in a PoE environment without an external power adapter. This reduces wiring complexity in fixed installation environments.
August 2025 โ Release of ADSBee GS3M PoE
https://pantsforbirds.com/adsbee-1090-august-2025-update/

In the August 2025 update, the ADSBee GS3M PoE model was released.

Aircraft transponder (1090 MHz / 978 MHz) โ RF frontend / comparator โ RP2040 PIO decoding โ internal protocol conversion / dictionary maintenance โ output (USB / UART / Wi-Fi, optional Ethernet) โ delivery to drones, applications, servers, or online databases
๐ Role and Application of the WIZnet's Chip
ADSBee uses WIZnetโs Ethernet controller, the W5500. The W5500 can be connected to the onboard ESP32-S3 via an SPI interface and serves as the network interface responsible for wired Ethernet communication.
In the overall ADSBee architecture, the RP2040 handles real-time decoding of ADS-B signals, while the ESP32-S3 is responsible for network and system control. Within this structure, the W5500 plays the role of delivering aircraft data processed by the ESP32-S3 to external networks via Ethernet.
By using the W5500, ADSBee is no longer dependent on a Wi-Fi environment and can achieve stable data transmission over wired LAN. When combined with a PoE expansion configuration, this enables ADSBee to function as a fixed receiver suitable for long-term, always-on operation.

๐ WIZnet Strategic Value
ADSBee is significant as a real-world example in which a WIZnet Ethernet chip is applied to an embedded aviation data collection system that operates in practice.
In particular, the fact that a project that initially centered on Wi-Fi expanded during development to a W5500-based Ethernet and PoE architecture can be seen as a natural illustration of the need for wired networks in field-installed embedded devices.
ADSBee has evolved beyond a simple demo or experimental level into a network node designed for long-term, always-on operation, with the W5500 playing the role of providing stable wired communication throughout this process. This demonstrates that the W5500 is well suited to the continuous operation, network reliability, and simple system configuration required in industrial and infrastructure environments.
In addition, the ADSBee architecture separates high-speed RF data processing (RP2040) from network processing (ESP32-S3 + W5500), making it a valuable structural reference that can be directly applied to other embedded network systems such as sensor nodes, remote monitoring devices, and data collection equipment.
Ultimately, ADSBee serves as an example within the WIZnet Maker ecosystem that shows a real development path in which a project that reached the limits of Wi-Fi expands to an Ethernet-based architecture, and provides concrete grounds for explaining the applicability of the W5500 to aviation, drone, and high-reliability data collection domains.
๐ Summary
ADSBee is a highly complete open-source ADS-B receiver with a clear role separation architecture consisting of the RP2040 (PIO decoding), ESP32-S3 (network processing), and WIZnet W5500 (Ethernet).
This demonstrates that WIZnet chips have been adopted in a reliable, real-world aviation data collection infrastructure.
๐ QnA
Q1. What is ADSBee 1090?
