USB ASP AVR Programmer for ATMEL Processors
The USB ASP AVR Programming Device for ATMEL processors is a USB in-circuit programmer for Atmel AVR controllers. USB ASP AVR Programming Device for ATMEL Processors simply consists of an ATMega88 or an ATMega8 and a couple of passive components. The programmer uses a firmware-only USB driver; no special USB controller is needed.
USB Charger Doctor Inline Voltmeter and Ammeter
Help! This patient is heating up! Is the voltage too low? Is the current draw too high? Is there a doctor in the house? Oh, thank goodness, the USB Charger Doctor (Voltmeter Ammeter) is here! Right on time Doctor, can you tell us what the current draw is? What about the voltage? Thanks to the Doctor, you will now be able to watch and care for your USB-powered projects.
Use the USB Charger Doctor to measure the working voltage and current output for any USB port and project. This blue plastic dongle plugs between a USB device and passes the data lines through. There is a 0.05-ohm resistor in line with the power pin that is used to measure current draw. The Doctors digital display instantly reads the numbers out for testing devices such as chargers, cables, and cell phones. You can use this device from the 3.5-7VDC input voltage (although most USB devices tend to hover around 4.75 to 5.25) and up to 3A of current. It flips between voltage and current readouts every 3 seconds or so. Its a very handy tool for testing USB devices, checking load levels and debugging battery chargers and boost converters. Its a little chunkier but more numerical thanour USB Power Gauge Mini-Kit. Its also not open source so check out the USB Power Gauge mini kit if you want to hack together your own power gauge indicator.

Standard size USB 2.0 socket mounted on a small PCB. No delicate soldering required. This USB connector can be easily attached to your projects
USB Logic Analyze 24M 8CH, MCU ARM FPGA DSP Debug Tool
USB Logic Analyze 24M 8CH, MCU ARM FPGA DSP debug tool is a very cheapest and useful debugging tool for digital signal analyzing, help you fully analyzing the UART, IIC, SPI, CAN all of these interfaces.
If you don't want to start with an expensive oscilloscope, this will be another good choice. A total of eight digital channels, the voltage range is 0V ~ 5.5V, the voltage threshold is considered to be low below 1.5V, 1.5V above is considered high.24 m sampling rate, can automatically analyze UART, IIC, SPI, and much other standard protocol.
If you do single-chip development, ARM system development or FPGA development then we strongly recommend you buy this product. To do a good job, must first sharpen his device MCU related products, as long as you do this tool will be your crescent moon nod. Especially do UART, SPI, IIC communication debugging, absolutely let you get twice the result with half the effort.
USB to RS232 Serial Converter 9 Pin Adapter for Win7/8/10
USB to RS485 Converter Adapter Module
The USB to RS485 Converter Adapter module support WIN7 XP Vista Linux Mac OS provides an easy to use RS485 interface by means of a Virtual Com Port on the users system.
There are no command structures, whatever is sent to the Virtual Comm Port is automatically converted to RS485 and vice versa. The module is completely self-powered from the USB bus. Controlling / Communicating with RS-485 devices from your PC has never been easier! This device is plug-and-play. It shows up as a serial/com port and is accessible from applications or hyper-terminal. This converter provides half-duplex RS-485 communication. The Baud rate range is 75 bps to 115200 bps, maximum up to 6 Mbps. No need of external power supply for operation.
USB to RS485 TTL Serial Converter Adapter FT232 Module
The USB to RS485 TTL Serial Converter Adapter FT232 Module is USB2.0 standard, backward compatible, in line with the standard RS485. It has Direction control with use of automatic data flow control, auto distinguish and control data transfer direction with Baud rate of 300-9216000bps and automatically detecting the serial signal data rate.
It supports the multipoint, each converter allows the RS485 interface device to connect 32 and comes with TVS tube Interface Protection and also with USB self-recovery protection. This USB to RS485 TTL Serial Converter provides two-way serial communications signal conversion between the RS485 to and from a personal computer USB port using virtual serial COM port. Self-powered from USB it uses FT232RL+75176 and can have up to 32 devices on the bus. The 4 jumpers connect the USB interface to the RS485 interface. If the jumpers are removed, the USB interface may be used as a TTL Level Serial port.
USB Ultrasonic Humidifiers Power Circuit Board with Atomizing Chip
This DC 5V Ultrasonic Humidifiers Power Circuit Board with Atomizing Chip Moisture Film Humidification atomization machine is; suitable for the atomization plate tablet with a diameter of 20mm.ThisUltrasonic Humidifier Piezoelectric Transmitter module works on the principle of cavitation produced by sound waves. Just provide the DC3-12V power supply it will turn into a mini ultrasonic atomizer.
Vibration Sensor Module SW-420
Vibration sensor module SW-420 based on the vibration sensor SW-420 and Comparator LM393 to detect if there is any vibration that beyond the threshold. The threshold can adjust using an onboard potentiometer. When this no vibration, this module output logic LOW the signal indicates LED light, and vice versa.
W1209 Digital Temperature Controller Thermostat Module
W1209 thermostat module has a temperature sensor, keys, LED display, relay and requires DC 12V power supply. It is an affordable, good quality thermostat controller. Thermostats are devices that sense the temperature of a system so that the temperature is maintained at the desired set point or near to it. NTC temperature sensor allows the module to intelligently control varied electrical devices based on the temperature. NTC thermistor has a negative temperature coefficient, which means the resistance decreases with increasing temperature. W1209 has an inbuilt embedded micro-controller, thus not much programming knowledge is required. The module consists of three switches to configure the various parameters including ON and OFF trigger temperatures. The relay can operate at voltages up to a maximum of 240V AC at 5A or 14V DC at 10A to power on. The temperature is displayed in degree centigrade and with the help of 7-segment display and the relay, the state is displayed with the help of the LED present on the W1209 module.
