Develop USB Host and Device applications with ESP32-S3-USB-OTG board

ESP32-S series chips like ESP32-S2 and ESP32-S3 come with a USB OTG interface, and Espressif unveiled the ESP32-S3-USB-OTG board last September in a post entitled “ESP-USB: Espressif’s Wireless Communication Solution“, where they mostly focused on USB code samples with documentation in Chinese only and provided few details about the board itself. But I browsed the company’s official Aliexpress store earlier this week, and I noticed ESP32-S3-USB-OTG board was up for sale for $35 plus shipping, with additional information now available, so let’s have a closer look. ESP32-S3-USB-OTG board specifications: Wireless module – ESP32-S3-MINI-1-N8 module with ESP32-S3 dual-core Xtensa LX7 processor with WiFi 4 and Bluetooth 5.0 connectivity, 8MB QSPI flash Storage – MicroSD card socket Display – 1.3-inch color LCD USB 1x Full-speed USB host port 1x Full-speed USB slave port 1x Micro USB port for debugging (UART console) Expansion – 14 pads with 6x GPIO, JTAG, 3.3V and GND […]

The cheapest Jasper Lake mini PC so far: JK01 for $140 and up

Intel Jasper Lake N-Series Celeron and Pentium processors were formally introduced at the beginning of the year as the successors of the Gemini Lake (Refresh) processors, and we’ve seen several mini PCs and motherboards so far from lesser-known Chinese manufacturers to more established brands like ASUS, GIGABYTE, and ECS. The previous generation Gemini Lake mini PCs would usually sell around $150 to $200, but now with the JK01 barebone computer, we’ve got an inexpensive Intel Celeron N5095 Jasper Lake mini PC selling for about $141 including shipping. CYX JK01 mini PC specifications: SoC – Intel Celeron N5095 quad-core Jasper Lake processor @ 2.0GHz / 2.9GHz (Turbo) with 4MB cache, 16EU Intel UHD Graphics; 15W TDP System Memory – 2x SO-DIMM slots for up to 16GB DDR4 memory Storage – M.2 2280 socket for NVMe or SATA SSD, 2.5-inch SATA drive bay, MicroSD card socket Video Output – 1x HDMI 2.0 […]

Stellar Data Recovery Professional for Windows could save your day (Sponsored)

Even if you backup your data regularly, data loss can still occur for a variety of reasons be it a power failure, a user mistake, hardware failure, or even viruses or malware like ransomware. But luckily there are professional data recovery software programs that could help save your day, or even your job, such as Stellar Data Recovery Professional for Windows, previously known as Stellar Phoenix Windows Data Recovery Professional, that can recover lost or deleted data from any storage media including HDDs, SSDs, USB drives & optical media (CD or DVD), and it even works with the latest Windows 11 operating system. Stellar Data Recovery Professional supports recovery from NTFS, exFAT and FAT (FAT16/FAT32) formatted drives, even on crashed and unbootable systems, and a new feature is data retrieval from a partially burnt or scratched CD/DVD. The software can restore all types of data including documents, emails, photos, videos, […]

A deep dive into Raspberry Pi Zero 2 W’s power consumption

Raspberry Pi Zero 2 W Power Consumption measurements with Otii Arc

When I completed my review of Raspberry Pi Zero 2 W, I mentioned I would test the power consumption of the board later. It took a while, but I’ve finally come around it using Otii Arc from Qoitech and Otii software to provide some pretty power consumption charts, and even energy consumption. Since the Raspberry Pi Foundation recommends a 5V/2.5A power supply, I’ll first try to get as close as possible as 2.5A, then I’ll go through tricks to reduce idle power consumption to less than 75 mA / 375 mW, and finally check the energy consumption under various CPU core count and frequency. Raspberry Pi Zero 2 W Power consumption under load, with accessories I started with the latest Raspberry Pi OS Lite “Bullseye” image and connected my Raspberry Pi Zero 2 W board to Qoitech Otii Arc tools as shown below. It used to cost around $500, but […]
