![]() The same chip is also used in the NanoVNA-F V2. In the picture to the left below, you can see an MS5351M I2C CMOS clock generator chip. The MCU used is a AT32F403 ARM Cortex M4F by ArteryTek. The inclusion of a microSD slot is certainly a welcome feature as it can be used to store screenshots during measurements.īelow, you can see the touch screen controller HR2046. This design makes it easy to debug/troubleshoot. ![]() Also note that all the header connections had been routed to the edge of the board. But the build quality looks quite decent.Īs can be seen in the picture to the left below, the touch screen included uses 4 wire resistive sensing. ![]() Unlike the NanoVNA-F V2 which is enclosed in a metal case, the LiteVNA comes in a plastic case with no additional shielding. Besides LCD screen sizes (2.8 inch for the 62 model versus 3.95 inch for the 64 model) and battery capacities (1.3 Ah for the 62 model versus 2 Ah for the 64 model), all other technical aspects are identical. LiteVNA current has two versions: LiteVNA 62 and LiteVNA 64. One of the key differences between the LiteVNA and the NanoVNA-F V2 is that LiteVNA has a frequency range from 50 kHz all the way to 6.3 GHz which essentially doubled the frequency range of the NanoVNA-F V2. This time let’s take a look at a LiteVNA vector network analyzer. In a previous post, I did a teardown of a NanoVNA-F V2.
