Industrial USB TO RS485 Bidirectional Converter
Overview
CH343G is a USB bus adapter chip, which can convert USB to a high-speed asynchronous serial port, supports automatic identification and dynamic self-adaptation of communication baud rate of 115200bps and below, and provides commonly-used MODEM contact signals to expand asynchronous serial ports for computers. It can upgrade a common serial device or MCU directly to a USB bus.
Features
- Support USB to RS485 bidirectional conversion
- Fast communication, stable and reliable, better compatibility
- Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightningproof & anti-electrostatic
- Onboard resettable fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, improves shock proof performance
- 3 LEDs for indicating the power and transceiver status

6 years and still going
Color: Blackout, Color: Blackout
Owned for 6 years and still going strong. Worn daily, including showers. The only time I take it off is to sleep. The face is scratched up and some buttons worn smooth (I wear it on the inside of my wrist). A few tiny cracks are beginning to form on one of the wristband pieces. Replaced the battery after about 3 years. It has three alarms and I use them regularly. You can choose to set each alarm for daily, weekdays, or weekends. I also use the timer a lot. Indiglo gets used every morning and many evenings. You can disable modes that you never use, so you only see what you want. I never use chronograph, so I have that disabled. Incredible watch.

The watch of our era
Color: Blackout
Bought this ‘used’ but looks like only the box had some ‘damage’ but the watch was perfectly brand new. I’ve been wearing a timex Ironman watch since my tenth birthday. I’ve served in the Marine corps and wore one while on tour. I’ve worn them snorkeling and diving. I’m a mechanic and have worn it on my belt loop while working, and depending what I’m doing I’ll leave it on. I wear it in the shower, the pool, beach, kayaking, skydiving, mudding, surfing, fishing, shooting, and while relaxing in my recliner. I’ve only had one battery die, and it was easily replaced.
This is the watch of our era. Stop reading this review and buy one!

Very dim
Color: Black/Yellow Accent
This was a gift for our son. The watch functions well, but I returned it because the screen was very hard to read.

Proud of my watch.
Color: G5885-silver-red, Color: G5885-silver-red
I purchased two of these and I am pleased so far.I was able to resize the band without any problems.They look good and I’ve received a few unsolicited compliments.IMHO they are well worth the 35 bucks or so I spent on them.Heck two of my buddies wearing r.l.x’s noticed them right off the bat.I just smiled and said thank you very much.
P.s.I could buy and sell my two friends many times over so didn’t bother me when they ask me the price.Proud of the good watch for the money.
