Al momento de escribir este post existen tarjetas que utilizan este chip en los modelos nano, uno y mega.Buy Zhongyu Mini USB CH340 Nano v3.0 3.0 ATmega328P Controller Board Compatible for Nano CH340 USB Driver Nano V3.0 ATmega328: USB Cables - FREE DELIVERY.The CH340C has 2 pins. The VCC pin and the V3 pin.CH340 IC is a low cost USB to TTL converter IC.
USB to TTL converter modules are also available based on this IC. Even Node MCU IOT modules also have this IC.We will be installing a USB to rs485 installation on our computer. The CH340/CH341 USB to serial port is a 2-wire USB to RS-485 serial communication adapter. The VCC pin can take in either 5V or 3.3V.
The problem here is that the CH340C output logic levels are referenced to VCC input. Therefore, we have the TX and RX pins working at 5V instead of 3.3V.Under normal circumstances, directly connecting the TX and RX lines to ESP32 or ESP8266 will kill the ESP chips because they are not supposed to work with 5V UART devices.However, in this case the CH340C pin output current is limited to 3mA only and the input logic-high threshold is low enough to allow the ESP to use 3.3V CMOS logic levels on the UART pins.This is the reason for connecting a 5V UART system directly to the ESP32 in the ESP32 CH340 programmer schematic. The clamping diodes on the ESP IOs can handle 3mA as per the datasheet.
To make the entire thing Arduino compatible, the microcontroller is an AtMega 328P, that can be connected to through the micro-USB port and CH340 USB-UART IC. Designed the clock with hacking in mind, opting to build it with components that many are already familiar with, such as a DS3231 RTC and WS2812 LEDs. By using 24 LEDs, MakeTime achieves a timing granularity of 2.5 minutes.The second purpose is as a development platform. Rather than displaying the time with digits, MakeTime harkens back to round dial clocks by illuminating RGB LEDs along its perimeter to show the position of the minute and hour “hands”. Is bringing the round face to digital clocks with his time-keeping piece, MakeTime.MakeTime serves two purposes, the first and most obvious one is as a clock.
There is, however, almost no English documentation, and the datasheet for the CH340 family doesn’t include this chip. The cheapest USB to serial chip on the market appears to be the CH340G, available for 20-40 cents apiece from the usual retailers. Posted in clock hacks Tagged 328p Atmega, CH340, clock, DS3231, pcb, time, ws2812FTDI-gate wasn’t great for anybody, and now with hardware hobbyists and technological tinkerers moving away from the most popular USB to serial adapter, some other chip has to fill the void. Check out the clock made out of ammeters we covered last week.
Usb Ch340 Series Of Chips
If you need the datasheet, here you go. This chip even has an IrDA mode, because wireless communication in the 90s was exactly as rad as you remember.With ’s help, we now have a cheap source of USB to serial chips. The chip supports 5V and 3.3V, and all the weird modem lines are supported. Isn’t that nice?The CH340 series of chips do exactly what you would expect them to do: a full-speed USB device that emulates a standard serial interface, with speeds from 50bps to 2Mpbs. He even made an Eagle part for you.
