I can personally not test on MacOS and can not vouch for the above drivers at github, but there you go.

#Ch341ser usb driver driver pre install falure drivers Here is an older version of the Mac driver, NOT FOR 10.12 Sierra See uninstalling information at the bottom of the page if the driver causes problems for you. (V1.0) Download the CH340 Macintosh Signed Driver for Mavericks (10.9), Yosemite (10.10) and El Capitan (10.11)ĭrivers are almost certainly built into your Linux kernel already and it will probably just work as soon as you plug it in. If not you can download the Linux CH340 Driver (but I’d recommend just upgrading your Linux install so that you get the “built in” one).Ī couple of Mac users have said “the driver crashes my mac Sierra how do I uninstall”.įirstly regards the crash make sure you installed the 1.3 version of the driver, not the old one. #Ch341ser usb driver driver pre install falure install Secondly a quick google search reveals that this is how you uninstall: You could download it directly from the Manufacturers Website in case they have issued an update since I wrote this page.

Open a terminal and type: cd /Library/Extensions/.

Kext file has been removed: ls | grep usbserial.kext kext file is present: ls | grep usbserial.kext

After you should remove the files stored in receipts folder: cd /private/var/db/receipts/.

340 is a USB converter chip, which converts USB to serial UART interface or to printer interface.

In UART mode, CH340 provides common MODEM interface signals, to expand UART interface of computer or upgrade common serial communication devices to USB directly. Full speed USB device interface, USB 2.0 compatible.įor more information about converting USB to printer interface, please refer to the datasheet CH340DS2.Emulate standard UART interface, used to upgrade the original serial devices or expand additional UART via USB.Original UART applications are totally compatible without any modification.Hardware full duplex serial UART interface, integrated transmit-receive buffer, supports communication baudrates varies from 50bps to 2Mbps.Supports common MODEM interface signals RTS, DTR, DCD, RI, DSR and CTS.Provides further RS232, RS485, RS422 interface, etc.

Through external voltage conversion chip. CH340R supports IrDA specification SIR infrared communication, supports baudrates varies from 2400bps to 115200bps.Software compatible with CH341, customers can use driver of CH341 directly.Supports 5V and 3.3V power supply even supports as low as 3V.CH340C/N/K/E and CH340B integrate 12MHz clock, no external crystal required, CH340B also integrates EEPROM used to configure the serial number, etc.RoHS compliant SOP-16, SOP-8, SSOP-20 and ESSOP-10, MSOP-10 lead-free package.ĬH340C, CH340N, CH340K, CH340E and CH340B integrate 12MHz clock, no external crystal required.ĬH340B integrates EEPROM used to configure the serial number, etc.#Ch341ser usb driver driver pre install falure serial The CH340K has three diodes built in to reduce current flow backwards between the I/O pins of the MCU. The backplane of the CH340K is 0# pin GND, which is an optional connection the 3# pin GND is the necessary connection.ĬH340R provides reverse polarity TXD and MODEM interface signals. #Ch341ser usb driver driver pre install falure drivers.#Ch341ser usb driver driver pre install falure serial.
