$1.80 CH551 Mini Development Board Features 8-bit C51 Core, USB Interface, and I/Os

Last year, WCH (Nanjing QinHeng Corp.)’s launched a CH55x family of microcontroller based on an 8-bit C51 core with a USB interface, and extra I/Os depending on the selected part number Electrodragon is now listing a tiny USB development board based on CH551 for $1.80, and the chip itself sells for as low as 1.60 RMB (0.25 USD) on Taobao. Specifications: MCU – WCH CH551 8-bit C51 micro-controller USB – 1x USB type A port I/Os – 18 through holes exposing all I/Os from the MCU including GPIOs, USB, 3.3V, 5V GND Misc – On-board power led, user LED (P3.0) Power – 5V via USB port (or pin?) You won’t need an external hardware – such as a USB to TTL board – to program the boards since the MCU supports USB. To enter into programming mode, short connect the two pins in the middle of the board (DL) with […]

Scrcpy Open Source Software Let You Control an Android Phone via a Windows, Mac OS, or Linux PC

Have you ever wished you could control or mirror your Android smartphone using your computer? Scrcpy, a free and open source program by Genymotion may fit your needs, and works on Windows, Mac OS or Linux. You just need to install (or build) a program on your host computer, connect your phone via USB, switch to developer mode, enable USB debugging, and run the program which will automatically install the server (a jar file) on your phone, which does not need to be rooted. The easiest way to try is with Windows since the developers already provide pre-built binaries, but I installed it on Ubuntu 16.04 instead since it is the operating system I use daily. Some of the packages in Ubuntu 16.04 are a bit old so it took me a couple of hours to successfully install it, and I’d recommend going with Ubuntu 17.10 or 18.04 daily build […]

ORICO 1088USJ3 Multi-Bay SATA to USB3.0 Enclosure Supports up to Ten 3.5″ Hard Drives

USB expansion drives and multi-bay NAS devices are both very common form of storage which have different applications, but I had never thought or seen multi-bay USB expansion drivers until I came across ORICO NS200U3 “2-bay USB 3.0 hard drive dock” on GearBest (~$82) that can handle two 3.5″ hard drives. This piqued my interest, so I went to ORICO website looking for models supporting more hard drives, and found ORICO 1088USJ3, a 10-bay USB 3.0 to SATA enclosure that can provide up to 80TB of local storage with 8TB drives. ORICO 1088USJ3 specifications: Storage – 10x SATA III slots up to 6 Gbps for 3.5″ HDD / SSD drive (up to 8TB per drive) Output Interface – USB 3.0 device port up to 5 Gbps Power Supply – 100-240V AC 50-60Hz Protection – Over-current, over-voltage, short circuit, overheat, and power leakage. Dimensions – 389(L) x 203(W) x 501(H)mm (aluminum […]

EasyVolts USB Dongle Outputs 0-24V DC, Exposes UART, GPIO/PWM, RS-485 Signals

A while ago, I wrote about USBminiPower, a USB power supply with 3.3V, 5V, and one variable DC output up to 14.3V adjustable with a rocker switch, and equipped for a 4-digit LED display showing current intensity and voltage. But recently, I was made aware of another USB power supply – EasyVolts USB dongle – that supports 0 to 24V DC, and also exposes either UART pins, or RS-485 signal, plus two GPIO/PWM pins. EasyVolts specifications: USB – 1x USB port for power, communication Power Supply function: Input voltage: 5V from USB port Output voltage: 0-24V Max output current: 1A Max output power: ~2.4W (e.g. 24V/0.1A; 3.3V/0.55A) Voltage resolution: <50mV Current resolution: <2mA I/O expansion 4- pin to be used as UART (Tx/Rx) or RS-485 + 2x GPIO/PWM UART – speed: 300-230400 bit/sec; resistance of Tx/Rx pins: 300 Ohm PWM – Base frequency: 240kHz.; frequency division configuration: 1-65535; duty cycle […]

Maiwo K104c is a $9 2.5″ SATA Drive Enclosure with a USB Type C Cable

USB type C receptacles are found in more and more devices, but if you have older accessories or peripherals they likely use micro USB, and USB type A cables or plugs. One way to work around this problem is to get adapter, for example, I purchased a micro USB to USB Type C adapter last year, but this morning I’ve come across a USB type C hard drive enclosure, something I had not seen before, probably because I did not look for it. Maiwo K104c enclosure specifications: Designed for 2.5″ SATA drives (HDD/SSD) up to 9.5mm thick USB type C to SATA 3.0 interface using JMS567 chipset UASP protocol support (aka USB attached SCSI) OS agnostic so it should work with any operating systems Dimensions – 21.50 x 2.70 x 1.20 cm Weight – 130 x 79 x 17mm JMicron JMS567 chipset is the same as used in NanoPi NEO […]
