This is the latest evolution of our serial LCD. Included on a single board is a 20x4 LCD and an embedded circuit based around a PIC 16F88. The on-board PIC takes a TTL serial input and prints the characters it receives onto the LCD. The installed firmware also allows for a number of special commands so you can clear the screen, adjust the backlight brightness, turn the display on/off, and more.

Communication with SerLCD requires 5V TTL serial at a default baud rate of 9600bps (8-N-1). You can adjust the baud to any standard rate between 2400 and 38400bps. The power (VDD), ground (GND) and RX pins are all broken out to both a 0.1" pitch header as well as a 3-pin JST connector.

SerLCD has the ability to dim the backlight to conserve power if needed. There is also a potentiometer on the back of the display to adjust the contrast.

  • Embedded PIC 16F88 utilizes onboard UART for greater communication accuracy

Decent Accessory Kit
Size: Eufy E25 Omni / E28 Omni E28, Size: Eufy E25 Omni / E28 Omni E28
This is a decent accessory kit I got for my E28! This kit comes with so many of the parts I needed to keep my E28 up and cleaning well. The accessories each fit my bot very well - the roller brush slid on with no issue and it didnt bind in any way. The knap on the brush is decent (a bit knappier than the OEM). This is nice because I have textured tile so a better knap will help clean inside the nooks and crannies. The kit comes with a lot of the needed items for the bot. One negative (but I didnt take away a star because this can happen in others as well) was that the cardboard on the dust bag didnt have enough glue to keep the bag on the stock board - it tore away super easily which was a bummer to lose a whole bag. Not the end of the world, but be carful inserting the bag properly to avoid tearing it away/open. All in all this is a decent kit and is a fraction of the price of others. Additionally, it is one of the least expensive kits on Amazon, which is nice - because we all could stand to save a buck or two.

Eufy Replacement Parts
Size: Eufy E25 Omni / E28 Omni E28, Size: Eufy E25 Omni / E28 Omni E28
The 14-piece replacement parts for the Eufy E25 Omni made a huge difference. It came with a roller mop, roller bushes, air filters, and dust bags. I hadn’t replaced any of my parts for quite a while and the vacuum was starting to not work very well. I ordered this set hoping for the best and was really impressed by the quality of the parts. Everything worked beautifully and installation was a breeze. After just a few seconds I replaced everything that needed to be changed and was scheduling for a cleaning. The new parts made a big difference in how well the vacuum performed and I couldn’t believe how much cleaner the floor was. I am totally happy with my order and will continue to use these parts.

Don’t buy
Size: Eufy E25 Omni / E28 Omni E28
Black roller brush doesn’t fit. Quality is not the same as eufy. The filter doesn’t have as many pleats ergo doesn’t filter as well.

Perfect Fit for Eufy E25 - Great Way to Refresh Your Vacuum
Size: Eufy E25 Omni / E28 Omni E28
This replacement kit worked perfectly with my Eufy E25 robot vacuum/mop. All of the parts fit as expected, and it was nice to be able to swap everything out at once rather than replacing pieces individually. After installing the new brush, mop, filters, and other components, my machine is running noticeably better. Super easy to do. The set includes a good assortment of replacement parts, making it a convenient way to refresh your vacuum and keep it working efficiently. A great value and an easy way to extend the life and performance of your robot vacuum.

Complete Replacement Set
Size: Eufy E25 Omni / E28 Omni E28
This replacement parts kit is a convenient way to keep a compatible robot vacuum running efficiently without having to source each component separately. The included rolling brush and side brushes help maintain strong cleaning performance by picking up debris effectively, while the filters support proper airflow and dust capture. The dust bags are a useful addition for keeping the self emptying system working smoothly over time. The roller mop also fits well and helps maintain the mopping function without needing frequent replacements. Having a full set like this makes routine maintenance much easier and helps extend the overall lifespan of the vacuum.
