$77 Intel Celeron N3350 mini PC ships with 4GB RAM, 64GB storage

cheap Intel mini PC 2023

Over around five years ago, it was relatively easy to find entry-level Intel mini PCs or PC sticks for less than $100, but in recent years, it’s been more of a challenge to purchase cheap Intel mini PCs unless when going the second-hand route. But there’s now a “DeskMini” mini PC selling for $77 (with a $12 coupon) on Amazon with the system being powered by an Intel Celeron N3350 Apollo Lake processor and coming with 4GB RAM and a 64GB eMMC flash preloaded with Windows 10. DeskMini specifications: SoC – Intel Celeron N3350 dual-core processor @ 1.1 GHz / 2.4 GHz with 12 EU Intel HD Graphics 500 @ 200 MHz / 650 MHz; 6W TDP System Memory – 4GB DDR4 Storage 64GB eMMC flash M.2 2242 socket for SATA SSD Full-size SD card slot Video Output – HDMI 1.4 port up to 4Kp30, VGA port; dual independent display […]

Arduino UNO R4 Minima and WiFi boards launched for $20 and $27.50

Arduino UNO R4 WiFi

Arduino UNO R4 Minima and WiFi boards powered by a Renesas RA4M1 32-bit Arm Cortex-M4F microcontroller and equipped with an optional ESP32-S3 WiFI & BLE module are now available for respectively $20 (18 Euros) and $27.50 (25 Euros) on the Arduino store. The Arduino UNO R4 Renesas RA4M1 board was initially unveiled during Arduino Day with most details, but not everything as the company had hidden one part of the board which we now know is for a 12×8 LED matrix and a Qwiic connector for expansion present on the UNO R4 WiFi only. Arduino UNO R4 specifications: Microcontroller – Renesas RA4M1 Arm Cortex-M4F MCU @ 48 MHz with 32KB SRAM, 256KB flash Wireless (Arduino UNO R4 WiFi only) – ESP32-S3-MINI-1 module based on ESP32-S3 dual-core Xtensa LX7 microcontroller with 512KB SRAM, 384KB ROM, WiFi 4 and Bluetooth 5.0 connectivity, PCB antenna Display (UNO R4 WiFi only) –  12×8 LED […]

Olimex ESP32-C6-EVB supports WiFi 6, BLE, Zigbee, comes with four relays, four opto-isolated inputs

Olimex ESP32-C6-EVB

Olimex ESP32-C6-EVB is an open-source hardware board based on an ESP32-C6 wireless module with 2.4 GHz WiFi 6, Bluetooth LE, and Zigbee connectivity, and offering four relays and four opto-isolated inputs, as well as further expansion via two UEXT connector. So far we had a limited amount of third-party ESP32-C6 boards, with Espressif making their own module and development board available in January, and 01Space launching a tiny ESP32-C6 board in April, a time when a lot of software work was still needed.  But the ESP-IDF v5.1 with ESP32-C6 support is nearing release (now RC2), and the Olimex board may mark the start of greater availability of ESP32-C6 hardware with stable/usable firmware. ESP32-C6-EVB specifications: Wireless module – ESP32-C6-WROOM-1-N4 module with Espressif Systems ESP32-C6 single core 32-bit RISC-V processor @ 160 MHz with 2.4 GHz WiFi 6 1T1R with Target Wake Time (TWT) support, Bluetooth LE 5.0, and 802.15.4 radio for […]

ASUS ExpertCenter PN42 mini PC with Intel Processor N100 launched for $220 and up

ASUS ExpertCenter PN42

We’ve covered several Intel Processor N100 mini PC, mostly from smaller Chinese companies with models such as the Morefine M9, the ZX01 Plus/Topton M6S, or the Beelink EQ12 which we reviewed with Windows 11, TrueNAS, pfSense, Ubuntu, etc… But if you prefer to rely on more established brands, the MSI Cubi N ADL is an option for $289 on Amazon with 4GB RAM and 128GB storage, or the ASUS ExpertCenter PN42 fanless Intel N100 mini PC which is now listed for pre-order on B&H for $220 and up. ASUS ExperCenter PN42 specifications: SoC – Intel Processor N100 quad-core Alder Lake-N processor @ up to 3.4 GHz (Turbo) with 6MB cache, 24EU Intel HD graphics; TDP: 6W System Memory – Up to 16GB single-channel DDR4 3200MHz memory via one SO-DIMM socket Storage – 1x M.2 22080 PCIe 3.0 x4 socket for NVMe SSD Video Output HDMI DisplayPort 1.4 up to 4Kp60 […]

Linux 6.4 release – Main changes, Arm, RISC-V and MIPS architectures

Linux 6.4 release

Linux 6.4 has just been released by Linus Torvalds on the Linux Kernel Mailing List (LKML): Hmm. Final week of 6.4 is done, and we’ve mainly got some netfilter fixes, some mm reverts, and a few tracing updates. There’s random small changes elsewhere: the usual architecture noise, a number of selftest updates, some filesystem fixes (btrfs, ksmb), etc. Most of the stuff in my mailbox the last week has been about upcoming things for 6.5, and I already have 15 pull requests pending. I appreciate all you proactive people. But that’s for tomorrow. Today we’re all busy build-testing the newest kernel release, and checking that it’s all good. Right? Released around two months ago, Linux 6.3 brought us AMD’s “automatic IBRS” Spectre defense mechanism, additional progress on the Rust front with User-mode Linux support (on x86-64 systems only), the NFS filesystem (both the client and server sides) gained support for […]

Intel soft router offers up to eight 2.5GbE ports, Comet Lake or Whiskey Lake Core processor

Intel mini router eight 2.5GbE ports

Topton is offering a soft router powered by an Intel Whiskey Lake or Comet Lake processor up to the Core i7-10510U quad-core/octa-thread processor with either eight 2.5GbE RJ45 ports or four 2.5GbE RJ45 ports and two 10GbE SFP+ cages. We’ve previously written about the low-cost InuoMicro G4305L8-S2 fanless industrial PC box with eight 2.5GbE interfaces, but it is powered by an Intel Celeron 4305UE dual-core Whiskey Lake processor, and the Topton model should offer more performance with a choice of 8th or 10th generation Intel Core i3/i5/i7 Whiskey Lake or Comet Lake SoC. Specifications: SoC (one or the other) Intel Core i3-8145UE dual-core Whiskey Lake processor up to 3.90 GHz with Intel UHD Graphics 620; 15W TDP Intel Core i5-10210U  quad-core/eight-thread Comet Lake processor @ 1.6 GHz / 3.9 GHz (turbo all cores) / 4.2 GHz (turbo one core), 24EU Intel UHD graphics; 6MB Cache; 15W TDP Intel Core i7-10510U […]
