What it is

This is a 3D-printable enclosure for Seeed Studio’s XIAO ESP32S3 & Wio-SX1262 kit. It turns two small boards into a compact Meshtastic node you can carry in a pocket. Adafruit featured the design in its #3DThursday post on November 12, 2026. The post notes that the same hardware can also work as a LoRa sensor node or a one-channel LoRaWAN gateway.

Adafruit’s headline calls the board a “XIAO ESP32S,” but the kit it covers is the XIAO ESP32S3 paired with the Wio-SX1262 LoRa module.

How it works

Boards: The Seeed Studio Wiki says the kit combines a XIAO ESP32S3 with a Wio-SX1262 LoRa module. The ESP32S3 runs the firmware, and the Wio-SX1262 handles the LoRa radio.
Radio: The Adafruit post lists operation at 868–915 MHz with a 2 dBi antenna.
Sensors: None come built in. The Seeed Studio Wiki says you can add GNSS and other modules through GPIO.
Motors: None. This is a radio node, not a moving build.
Code: The kit runs Meshtastic firmware. One retailer says the kit ships pre-flashed, so you may not need to flash it yourself. Check your listing.
Size: The Seeed Studio Wiki gives the kit as about 22 × 23 × 57 mm. Seeed’s own version uses a black ABS enclosure.

Parts list

Part	Role	Rough price
Seeed Studio XIAO ESP32S3 & Wio-SX1262 Kit	Main board plus LoRa radio	About $29.49 to $55.99, depending on retailer (one listing at about $29.49, Newegg at $55.99)
868–915 MHz antenna, 2 dBi	LoRa antenna, as listed in the Adafruit post	Check your kit listing for what is included
Printed case (files on MakerWorld)	Enclosure	A small amount of filament
Optional GNSS or other module	Adds location or other features via GPIO	Varies

How to build your own

Difficulty: Easy
Time: About 34 minutes of printing, plus a short assembly
Skills: Basic 3D printing, handling small boards, and setting up Meshtastic

Steps at a high level:

Get the right kit. Buy the XIAO ESP32S3 & Wio-SX1262 version. The Seeed Studio Wiki warns that the Wio-SX1262 from the nRF52840 kit does not work with the ESP32S3 version, so don’t mix parts between the two.
Download the case. The files featured by Adafruit are hosted on MakerWorld. Seeed Studio also publishes its own case model for this kit on Printables, along with several community cases for the same boards.
Print it. The Adafruit post gives a sample profile of 0.2 mm layers and 15% infill. That profile takes about 34 minutes on one plate.
Check the firmware. If your kit came pre-flashed with Meshtastic, you can skip this. If not, flash Meshtastic onto the ESP32S3.
Set your region. Choose the band and region that match the rules where you live, within the 868–915 MHz range.
Assemble. Fit the boards into the case and attach the antenna. Retail listings suggest this is snap-together or simple assembly.
Join the mesh. Pair the node with the Meshtastic app and look for other nodes nearby.

What we would change

Add a screen. A community case on Printables includes an OLED display. That is handy if you want to read messages without a phone.
Plan for GNSS. The kit supports GNSS through GPIO. We’d like a case variant with a dedicated spot for a GNSS module, so position sharing works without an extra phone.
Print it tougher for outdoor use. Seeed’s own enclosure uses ABS. If your node will live in a hot car or outdoors, consider a more heat-tolerant filament than the usual PLA.
Label the band on the case. The kit spans 868–915 MHz. A small embossed region marker would help anyone who builds more than one node.

This build is not ours. We are spotlighting it because readers can easily copy it.

The design was featured on the Adafruit Industries blog in its #3DThursday post of November 12, 2026. The model files are hosted on MakerWorld. We could not confirm the designer’s name from the Adafruit post, so please visit the MakerWorld listing to credit the maker directly.
