wafer.space lets you design your custom silicon just for $7 per die (Crowdfunding)
wafer.space has launched its first pooled silicon fabrication run on Crowd Supply, called the GF180MCU Run 1, which enables designers, engineers, and companies to create 1,000 custom ASICs using GlobalFoundries’ 180 nm mixed-signal process. Each slot provides a fixed 3.88 × 5.07 mm (19.67 mm²) die area replicated 1,000 times, meaning you will receive 1000 chips, with options for bare dies or chip-on-board packaging. The GF180MCU process supports 5 metal layers, MIM capacitors (~2.0 fF/µm²), poly and high-res poly resistors, and standard-Vt MOS devices. Users can handle their own pad ring, ESD, and I/O layout while wafer.space manages fabrication, dicing,...

The latest Raspberry Pi OS images are now based on Debian 13 “Trixie”
Since Debian 13 “Trixie” was released last August, it was just a matter of time until Raspberry Pi OS followed. Raspberry Pi announced the update from Bookworm to Trixie a few days ago. The new Raspberry Pi OS images get the new and updated packages from Debian 13, and features like 64-bit time support to solve the Y2K38 bug. However, as Simon Long, UX engineer at Raspberry Pi, points out, there have been fewer changes in newer versions of Debian, and most changes in the new version of Pi OS are cosmetic, although there are some interesting under-the-hood changes as...
1GHz Renesas RA8T2 Cortex-M85 MCUs feature MRAM and EtherCAT for industrial motor control
Renesas has recently introduced the new RA8T2, an AI-powered motor control Cortex-M85 MCU that can be considered a direct upgrade to the RA8T1, which launched last year. The RA8T2 offers higher performance along with networking options for industrial, robotics, and other motor control systems. The RA8T2 features a 1GHz Arm Cortex-M85 core, an optional 250MHz Cortex-M33 core, up to 1MB MRAM and 2MB SRAM, a 300MHz PWM timer, dual 16-bit ADCs with simultaneous sampling, high-speed comparators, fast PWM shutdown, and more. Connectivity options include dual Gigabit Ethernet, EtherCAT slave, USB, CAN FD, I3C, and SPI, while security features include TrustZone...
Easily add 80+ Mbps Ethernet to microcontrollers with WIZ630io QSPI RJ45 module
WIZnet WIZ630io is a small module featuring an RJ45 jack and a W6300 controller supporting up to 80+ Mbps Ethernet over QSPI @ 150 MHz. As a reminder, the W6300 features 64KB of SRAM for 8 sockets, each with a 4KB TX/RX buffer by default. It is notably found in the WIZnet W6300-EVB-Pico2 development board powered by a Raspberry Pi RP2350 MCU. The WIZ630io allows you to easily add Ethernet to any RP2350 board or other microcontroller with a SPI or QSPI interface. WIZnet WIZ630io specifications: W6300 QSPI Ethernet controller Host Interface – High-speed QSPI (MODE 0/3), system bus with...

Developed and assembled in Atlanta, it is the company’s first model built on a custom PCB featuring a dedicated I/O controller and integrated power management. The unit is powered by a Nordic nRF52840 microcontroller paired […]
kv4p HT – Turn an Android smartphone into a ham radio transceiver
kv4p HT is an open-source hardware VHF or UHF radio designed to plug into the USB-C port of an Android smartphone and turn it into a handheld ham radio transceiver. It’s based on an ESP32 wireless module and an SA818 radio module. This accessory makes your phone capable of off-grid voice and text communication with a Technician-class amateur radio license. It’s small enough to fit into a pocket, partially because it does not need a battery, relying on the built-in battery of your phone. kv4p HT V2.0 specifications: Wireless module – ESP32-WROOM-32E-N4 SoC – ESP32 dual-core Tensilica LX6 microcontroller @...
Linux-based Vega OS replaces Android-based Fire OS in Amazon Fire TV Stick 4K Select
Amazon has recently introduced the Fire TV Stick 4K Select media streamer with a MediaTek MT8698 quad-core Cortex-A55 processor, 1GB RAM, 8GB eMMC flash, HDMI 2.1 video output, and WiFi 5 and Bluetooth 5.0 connectivity. However, the most interesting part of the announcement is the software, as Amazon has dropped the Android-based Fire OS used in its previous devices and instead relies on the new Linux-based Vega OS for the Fire TV Stick 4K Select. Amazon Fire TV Stick 4K Select (AFTCA002) specifications: SoC – MediaTek MT8698 MCM CPU – Quad-core Arm Cortex-A55 clocked up to 1.7 GHz GPU –...
Free Stuff - July 2025
The belated July 2025 recipient for the Great Scott Gadgets Free Stuff Program is Murat Sever, a professor from Turkey who teaches at TOBB ETU University and recently ran a workshop titled “Simple Replay Attack Demo with GNU Radio.” In this workshop, Murat utilized several open-source software and hardware tools to demonstrate how to receive and transmit RF signals. Workshop participants then used SDR and GNU Radio to perform replay attacks with the captured radio signals. We sent a handful of HackRF Ones to Murat for participants to learn and experiment with in this workshop. He has also informed us...
