What it is

PMSG turns any pair of eyewear or cool pair of without sunglasses into modular smart glasses customisable, open-design and ultra-accessible. It’s a wearable face computing platform powered by Seeed Studio XIAO MCUs or similar  xiao headers with BLE, Wi-Fi, LoRa and optional sensors. Easy add ons via grove ports

Key Features

• 🕶️ Modular & DIY: Swap arms and add sensors or displays with Grove-compatible connectors.  
• 📡 Connectivity: BLE, Wi-Fi, LoRa and USB-C for notifications, data and power.  
• ⚙️ Open: Hardware designs + firmware you can build or modify.  
• 📲 Mobile Interactions: Connect to phones for BLE notifications and custom apps.  

Why PMSG

PMSG is designed to make smart glasses accessible  not locked to a single vendor or pricey hardware. It’s ideal for DIY tech, sensor experiments, notifications, environment sensing, or bespoke wearables.  *( The Arduino like and Raspberry PI for on your face like the xiao rp2040 model you can add )

PMSG is a modular platform where users can experiment with different wireless technologies. We test multiple RF modules — including Wi-Fi, Bluetooth (2.4 GHz), LoRa, and cellular — in a plug-and-play setup, so anyone can swap modules like LEGO blocks and find the best fit for their use case.

📡 But we don’t stop at chips  you can also experiment with RF antennas. PMSG’s breadboard-friendly layout lets you try different antenna types and models to see what works best for your signal, range, and environment. 

Available antenna options for PMSG testing include:

• Whip antenna — for Wi-Fi (2.4 GHz) and IC antenna setups

• SMA connector antennas — for LoRa or Wi-Fi configurations

• LoRa antennas printed on flex PCBs — ultra-compact and wearable-friendly

• External LoRa whip antennas — for extended range experiments

• External Bluetooth whip antennas — for reliable short-range connectivity
  

• External cellular (LTE/NB-IoT) antennas — for wide-area coverage and mobile network testing

Type of PMSG models 2024/2025 

We love pushing boundaries in wearable tech. For our PMSG Smart Glasses, we’re experimenting with replacing parts of traditional PCB epoxy with aluminium  inspired by Without® — to make our hardware more recyclable, skin-friendly, and comfortable to wear.

This aluminium PCBA experiment is just one of many steps in our mission to make wearable electronics smarter, more sustainable, and more human-centric.

What’s Next

Our first small batch of PMSG Smart Glasses is on the way. Meanwhile, we’re building up our digital home at pmsg.online, where we’ll share more updates, experiments, and collaborations. And we also like to use vibe-coding and "MCPLINK" or MCPbuttons to get you going 

Just choose an AI link (ChatGPT, Gemini, or Grok) and you’ll open a ready-made setup guide tailored to your hardware — plug in your details and build.
