microSD-express Pi Adapter is an ultra-small microSD Express adapter for the Raspberry Pi 5

We’ve just written about Will Whang’s RPI5-SDexpress-Hat board, which adds a microSD Express slot to the Raspberry Pi 5, but it’s not that small, and it’s using the 40-pin GPIO for power, so it’s not convenient if you want to install another Raspberry Pi HAT+. Vassily Petrov’s “microSD-express Pi Adapter” is a much smaller microSD Express adapter on a flexible PCB that plugs directly into the PCIe FFC connector and nothing else, driving power from the PCIe connector only. There’s not much on the PCB itself besides a microSD Express card slot and a Microchip MIC2230 800mA/800mA step-down DC/DC regulator. ...

Decoding Meshtastic with GNURadio on a Raspberry Pi

Decoding Meshtastic with GNURadio on a Raspberry Pi

I've been playing with Meshtastic a lot, since learning about it at Open Sauce last year. I'm up to 5 little LoRa radios now, and I'm working on a couple nicer antenna placements, so I can hopefully help shore up some of the north-south connections on the MeshSTL map.

To better understand the protocol, I wanted to visualize Meshtastic communications using SDR (Software Defined Radio). I can do it on a Mac or PC, just setting GQRX, SDR++, or SDR#, and watching...

Neuro PlayGround Lite – A multichannel wireless bio-signal capture board for HCI & BCI projects (Crowdfunding)

Neuro PlayGround Lite, or NPG Lite for short, is an ESP32-C6-powered multichannel wireless bio-signal capture board designed for HCI (Human-Computer Interface) and BCI (Brain Computer Interface) projects and applications. It can capture Electrocardiography (ECG), Electromyography (EMG), Electrooculography (EOG), or Electroencephalography (EEG) signals, and the ESP32-C6-MINI-1 module used in the design supports 2.4 GHz WiFi 6, Bluetooth LE, Zigbee, and Thread for mesh networking. It also follows the Adafruit Feather form factor, so it can be expanded with FeatherWings add-ons, including the company’s Playmate boards. Neuro PlayGround Lite specifications: Wireless Module – Espressif Systems ESP32-C6-MINI-1-N4 SoC – Espressif Systems ESP32-C6 CPU...

AAEON PICO-MTU4-SEMI may be the world’s smallest Intel Core Ultra mini PC

AAEON PICO-MTU4-SEMI is said to be the world’s smallest mini PC powered by an Intel Core Ultra processor at just 108 x 95 x 43mm in size. It ships with an Intel Core Ultra 5 125U 12-core Meteor Lake processor, up to 32GB LPDDR5 memory,  supports M.2 2280 NVMe (or SATA) SSD storage, and offers 2.5GbE and GbE ports, a Key-E socket for wireless connectivity or AI accelerator, HDMI 1.4 video output, two USB 3.2 ports, and two RS232/RS422/RS485 COM ports. PICO-MTU4-SEMI specifications: SoC – Intel Core Ultra 5 125U CPU – 12-core (2P+8E+2LPE) Meteor Lake-U processor @ 1.3 /...

Seeed Studio XIAO nRF54L15 USB-C boards support Matter, Thread, Zigbee, and Amazon Sidewalk

Seeed Studio recently introduced the XIAO nRF54L15 series, which includes the XIAO nRF54L15 and XIAO nRF54L15 Sense USB-C development boards.
