Original GroundStudio product

The products created by GroundStudio are made using high quality components, they are designed and assembled in Romania.

Product description:

The USB to Serial converter module is based on the HT42B534-2 integrated circuit. Most of the time, the module is used to connect a microcontroller or a development board to the computer (Pro Mini, ESP8266, ESP32, etc.)

The module can also be used to emulate another device (e.g. a keyboard) using the program and documentation available at the following link: https://www.holtek.com/productdetail/-/vg/HT42B534-2

The product converts signals from the USB protocol to the Serial protocol and vice versa. It can work both on the logical level of 3.3V and on that of 5V (the voltage is selectable by jumper).

The presence of the supply voltage is indicated by the "PWR" led and the presence of the signal on the Rx and Tx serial communication lines is indicated by the "RTX" led.

For cases where consumption is desired to be minimized, the two LEDs can be disconnected individually using the RTX and PWR DISABLE LEDs jumpers located on the back of the pcb.

Technical specifications:

Supply voltage: 3.3V or 5V

For 5V, the current will be supplied directly by the USB port to which it is connected (maximum 500mA)
For 3V3 current will be provided by the stabilizer on the module (maximum 500mA)
Dimensions approx: 39.2mm x 19mm
4x M2 screw mounting holes [27mm x 14.76mm]

* It does not require the installation of an additional driver on any operating system (unlike other modules on the market (CH340, FTDI, etc)).
