VK2828U7G5LF weight is about 14g, in the same with the specifications of the products is the smallest, performance is strongest, the most exquisite GPS module. Built-in fast 50 satellite positioning and tracking ability ublox chip, the built-in battery backup, built-in high gain LNA, the "double road, PCB zedoary process, large area radiation GPS signal, not the locator. Signal is better and more stable. With optional baud rate, 4800, 9600, 19200, 384,00, 5700, 115200 and so on rate and RMC, GSV, GSA, GGA, vacations, GLL statements, such as free combination, let you use this product more easily. Default output of 9600 standard.
