📅 2025 Year in Review

What a year it’s been! Sometimes I have a hard time believing just how much stuff gets crammed into 365 days, and Pants for Birds had an exceptional rate of year per year in 2025.

January: ADSBee added multi-core support, network improvements, and faster CRC decoding + correction.

February: ADSBee switched to a formally verified CPR position decoder, and we sold out of the original ADSBee 1090.

March: I went to Shenzhen and ADSBee rode a weather balloon! These were unrelated events.

April: We added a new lighweight dipole antenna to the store. Behind the scenes, I was panic-redoing the entire dual band ADSBee hardware design from scratch due to a dead end with a sub-GHz radio IC I had thrown quite a bit of time into. Simultaneously, all hell broke loose in hardware land with the beginning of the 2025 trade war and “reciprocal” tariffs.

May: We debuted a number of new hardware designs, including the dual band ADSBee 1090U, the ADSBee m1090 solder down module, ADSBee PoE pant, and a breakout board for the new ADSBee 1090U’s high density debug connector. We also introduced custom designed PCB antennas for 1090MHz and 978MHz!

June: ADSBee 1090U entered production, and the first PoE pant prototypes were brought up successfully (with a little bit of rework).

July: ADSBee went to Open Sauce! My friends and I met hundreds of very cool people, and a shoutout on Jeff Geerling’s second youtube channel introduced ADSBee to many people for the first time. We also built a functioning miniature cockpit display with ADSBee in collaboration with FPVToys.net, and introduced MLAT-grade timestamps with some cursed PIO + DMA hackery, enabling the ADSBee to be used as part of a receiver array that can track aircraft transponder locations via time of flight.

August: We introduced our weatherproof outdoor ADS-B receiver, the GS3M PoE, and also debuted our own ADS-B aggregator website for testing ADSBees, whereplane.xyz!

September: ADSBee attended Commercial UAV Expo in Las Vegas, where we won an award in their “Pitch the Press” competition for innovative products, and also exhibited at Bay Area Maker Faire! The ADSBee PoE pant also had its first production run, and we introduced the indoor PoE receiver bundle in the web shop. On the firmware side of things, UAT packets were added to Mode S Beast feeds via a custom packet format that was developed in collaboration with @wiedehopf, the maintainer of many popular open source software packages that are used by online ADSB aggregators.

October: We had some adventures in IPX5 testing for the GS3M PoE, and ADSBee was featured in Make Magazine! We also debuted the ADSBee m1090 eval board in the web store, allowing customers to easily prototype applications based on the m1090 module, and ran a new production run of ADSBee 1090U’s with a BOM revision that improved high temperature operation and enabled a lower input voltage to be used (great for battery powered applications).

November: I put a GS3M PoE on my roof, and it works great! We also debuted a firmware update that significantly retooled PIO preamble detector and demoulator performance and added filters for improving position tracking performance on UAT.

December: That’s this month!

💾 Firmware Updates

This month, we’ve released firmware version 0.9.0-rc5, which includes some buffer safety improvements, some behind-the-scenes fixes to make programming ADSBee m1090 modules on the production line easier, and TIS-B / FIS-B forwarding over WiFi! If you have an Electronic Flight Bag (EFB) device with ForeFlight or a similar EFB app that can accept TIS-B / FIS-B data over GDL90, we would love to hear some test feedback, as these packets can be hard to capture unless you’re in range of a UAT uplink broadcast facility.

🔧 Hardware Updates

📡 GS3M PoE In Stock and Shipping!

At long last, the GS3M PoE is in stock and shipping to customers! I’m very excited to see more of these going out into the field. If you’re in the market for an industrial weatherproof ADS-B receiver, the GS3M PoE will happily do the job.

🧩 ADSBee m1090 Individual Modules Now Available

* Begin David Attenborough Voice *

The young, unprogrammed ADSBee m1090 wanders across the workbench in search of data, but stops to investigate a new oddity. Some kind of new cavern has appeared, with shiny, round pogo pins that seem to beckon a closer look.

Chomp!

The m1090 is squeezed tight, and before it has a chance to wriggle free, is injected with a new firmware.

010250007A-20250409-030011 wakes up with a start. What a terrible dream. Did it used to be an unprogrammed RP2040? Without a serial number? What a crazy idea. No time to dwell on it–there’s a background whisper that has become a roar, and it needs to be listened to. Airplanes.

* End David Attenborough Voice *

With the completion of a cool custom test fixture, pre-programmed and tested ADSBee m1090 modules are now available! The initial batch of prototypes is just about sold out, but I am kicking off a domestic production run shortly that will make them more widely available. Once the current stock runs out, backorders should be filled within January.

If you’re interested in ordering more than a small handful of ADSBee m1090 modules, please get in touch with me for volume pricing! Price breaks at various volumes and production locations are available depending on your needs.

🧩 ADSBee m1090 Eval Boards Back in Stock

A small production run of m1090 Eval Boards was completed using a portion of the remaining m1090 prototypes, and is now available! If you’re looking to try out the ADSBee m1090 for your custom application, it’s got everything you need to poke and prod the module to your heart’s content (and hook up external development boards to extend the m1090’s functionality).

If you’re curious about what cursed wire ratsnest allows you to turn the m1090 Eval Board into a full-featured ADSBee 1090U (but in more pieces), take a look at the brand new ADSBee m1090 Eval Board datasheet!

❤️ Thanks!

I want to express my gratitude to everyone who has made this year a wonderful lap around the sun for the ADSBee project. It’s been extremely rewarding to hear from so many people who are excited about open source ADS-B, be it on Discord, in person at trade shows and events, or via email. I’m excited for what 2026 has in store!
