All module pins broken out - On-board FTDI USB-to-Serial.
802.11 b/g/n - Wi-Fi Direct (P2P), soft-AP.
Integrated TR switch, balun, LNA, power amplifier and matching network - Integrated PLLs, regulators, DCXO and power management units.
Integrated low power 32-bit CPU could be used as application processor.

Works with Windows,Andorid,Linux,Raspberry pi.Support Google Earth.It can not work with IOS system..
The default output is the product GPs protocol data. You can test the software or serial commands to modify switch PS / GLONASS protocol data..
Note: This dongle only can work outdoor. If you want to let it work indoor, you need have GPS amplifier. Otherwise the GPS can not lock..

The master-slave module has three functions of transparent transmission, remote control and PIO acquisition. It can be switched and set through the AT command set. It is easy to use the same as the Bluetooth serial port module you have used before, without changing the PCB and the lower computer program..
Support AT command, users can change the serial port baud rate, device name, pairing password and other parameters as needed, use flexible..
Support UART/I2C interface, and support SPP Bluetooth serial port protocol, has the advantages of low cost, small size, low power consumption, high sensitivity of sending and receiving, etc., only need to be equipped with a few peripheral components to achieve its powerful functions..
This module is mainly used in the field of short-distance data wireless transmission. It can be easily connected to the Bluetooth device of the PC, or the data between the two modules can be intercommunicated..
When the Bluetooth connection is not established, the baud rate, name, and pairing password can be set by the AT command. After the setting, the parameter is saved after power-off, and the Bluetooth connection automatically switches to the transparent transmission mode..

Machine introduction: LA104 is a four-channel logic analyzer with built-in screen and battery. The casing of LA104 is made of aluminum alloy through CNC..
Easy to use: It is compact and portable, making it easy for users to work on bench or outdoors..
The effect is obvious:LA104 has a 2.8-inch LCD display that allows the measured logic waveform to show directly on the screen, without connecting to other external display devices..
Multiple trigger modes: There are three serial protocol analyses: SPI, I2C, UART, supporting user-defined protocol mode.
Muti-functional: suitable for digital hardware verification and debugging, monitoring, measurement and optimization of digital hardware performance, and integration, debugging and verification of embedded software..

This usb gps works with Windows, Linux, Raspberry PI and Google Earth, not for IOS Android.
The vk-172 gps is NOT plug and play for most device. You need to install driver before make it work. Raspberry Pi and linux no need driver..
VK-172 automatically adapt the baud rate, The baud rate has any data output..
The default output is GPS protocol data,you can modify the PS/GLONASS protocol data by testing software or serial commands..
VK-172 built-in high-gain LNA, dual-channel LDO, large area radiation GPS optional baud rate 4800, 9600, 19200, 38400, 5700, 115200, etc..
