Epi 32U4 – An Arduino-compatible USB-C development board with ATmega32U4 MCU (Crowdfunding)

Epi 32U4 Arduino USB Type-C development board

Epi 32U4 is a tiny Arduino-compatible development board based on a Microchip ATmega32U4 8-bit AVR microcontroller with just a USB-Type-C port and 23 I/O pins accessible through castellated holes that can be soldered to headers or another PCB. The board also includes some protection such as a fuse, ESD protection, a ferrite bead, and a low-pass filter for the analog reference voltage. Ping Hobbyelektronik, the developer, says it’s especially useful for compact USB keyboards, but it also has more I/O ports than a standard Pro Micro board, so it’s appropriate for a range of other projects as well. Epi 32U4 board specifications: MCU – Microchip ATmega32U4 8-bit AVR microcontroller @ 8MHz or 16 MHz with 32 KB flash, 2.5 KB SRAM, 1 KB EEPROM USB 1x USB Type-C port for power and programming USB D+ and D- lines are broken out ESD and surge protection on USB data lines and […]

Silicon Labs FG28 Sub-GHz wireless and 2.4 GHz BLE SoC supports Amazon Sidewalk, Wi-SUN, etc…

Silicon Labs dual-band FG28 Cortex-M33 SoC comes with sub-Gigahertz and 2.4 GHz Bluetooth LE radios that support long-range networks and protocols like Amazon Sidewalk, Wi-SUN, and other proprietary protocols, as well as a built-in AI/ML accelerator for machine learning inference and SiLabs Secure Vault technology. The chip looks to be an update to the sub-GHz FG25 Cortex-M33 microcontroller with an additional 2.4 GHz BLE radio, but somehow less program memory (up to 256KB) and storage (up to 1024 KB). The peripherals implemented in the chip are almost the same, as the microcontroller gains support for predictive maintenance with a small matrix vector processor for AI/ML acceleration. Silicon Labs FG28 (EFR32FG28) specifications: MCU core – Arm Cortex-M33 @ 78 MHz with DSP instructions and FPU On-chip memory – Up to 256 kB RAM data memory On-chip storage – Up to 1024 kB flash program memory AI accelerator – Matrix Vector Processor […]

GEEKOM AS 6 review – Part 2: An AMD Ryzen 9 6900HX mini PC tested with Windows 11 Pro

We’ve previously checked out the hardware of the GEEKOM AS 6 mini PC, the retail version of the ASUS PN53, using an AMD Ryzen 9 6900HX CPU with unboxing, teardown, and the first boot in the first part of the review. We’ve now spent more time with Windows 11 Pro on GEEKOM AS 6 for a thorough review, it’s one of the fastest mini PCs we’ve tested so far, and there are only a few downsides as we’ll see in the second part of the review. Software overview and features testing Our GEEKOM AS 6 sample shipped with Windows 11 Pro 21H2 build 22000.1281, and Windows system information confirms we have a system with a 3.3 GHz AMD Ryzen 9 6900HX CPU and 32GB RAM. If we look at more details, we can confirm the reported specifications match the advertised ones with an 8-core/16-thread CPU, an ASUS PN53 motherboard, etc… […]
