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

Letdown after ESA & OGS but Still a Great Summer Read
Format: Hardcover
Highly anticipated after 2025's One Golden Summer sequel to Every Summer After because The Florek boys are everything. Loved the setting (Tofino sounds gorgeous), but the book was off balance. Long-suffering George was so thoughtful & obviously in love with his BFF Frankie. Other than shared history, I wondered why. She's supposed to be independent (as was Jo in her fave book Little Women), but she spends a lot of time sobbing, moping, resenting, & pushing everyone away. She's oblivious to George's obvious devotion even when he's traveling the world for work & firmly consigns him to the friend zone (but doesn't date anyone else beyond a device driven brief engagement to wildly unsuitable guy). At 30, she still thinks romance will kill their 22 yr friendship? Even their magical week in Tofino when they're together is unsettled by her reticence & constant disbelief they can be a couple. There are a lot of flashbacks to the besties at 8, 12, 16, 20, & last year that disrupt the flow & don't serve the story. Still, she writes beautiful sentences and has the ability to transport. It's a good book, just a 4 not a 5.

George was awesome...the setting was beautiful...not a fan of Frankie
Format: Hardcover
I had to buy this book since One Golden Summer was amazing and stayed with me longer after I finished it.
In this book, the setting and descriptive scenery of their honeymoon destination and how it was woven into the story was the highlight. The romance took second place and was lackluster overall as I never really connected with why Frankie was such a good friend and George fell in love with her. The ending was just okay and I think the letters could have been better utilized in the story instead of dumped in at the end. The whale storyline was a footnote and distracted from the story. It could have been a few chapters shorter overall. I loved George and felt like he deserved better.

Fabulous

OH, GEORGE!!! 😮💨🫠 What a perfect friends to lovers summery romance. Fortune has become a fast favorite of mine to just make my heart ache. Yes, Frankie is oblivious, slow and frustrating at times but it was such a lovely, scenic and magical story! 🥰🥰🥰

predictable but enjoyable
Format: Kindle
Very obvious plot, but still enjoyed the character and storyline development. If you’re looking for a mindless, easy romance then I would recommend this.

This stuff really works — turns sunburn into a tan! ☀️🌺⭐️⭐️⭐️⭐️⭐️
I was skeptical, but this really does what it says! I got a little too much sun and used this right after showering no peeling, no pain, and within a day or two, my skin turned a gorgeous golden brown instead of burning. It feels soothing, smells great, and absorbs quickly without being sticky. Definitely a must-have for beach trips or after any sun exposure. I’ll never go without it again!
