sku: LCD-09067
The serial enabled LCD allows you to control a parallel based LCD over a single-wire serial interface. Included in this product is a white on black 16x2 LCD connected to our serial backpack. The backpack, based around a PIC16LF88, takes a TTL serial input and prints the characters it receives onto the LCD. The installed firmware 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 3.3V 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, ground and RX pins are all broken out to a 3.5mm pitch screw terminal.
SerLCD has the ability to dim the backlight to conserve power if needed. There is also a potentiometer on the backpack to adjust the contrast.
Note: Though the silkscreen may say '5V', this is a 3.3v Serial LCD. Connect to a 3.3v power source.
Features
- PIC 16LF88 utilizes onboard UART for greater communication accuracy
- Greater processing speed at 10MHz
- Incoming buffer stores up to 80 characters
- Backlight transistor can handle up to 1A
- Pulse width modulation of backlight allows direct control of backlight brightness and current consumption
- All surface mount design allows a backpack that is half the size of the original
- Faster boot-up time
- Boot-up display can be turned on/off via firmware
Dimensions: 1.425x3.15" - 1" Thick

My everyday espresso bean — fresh-ground changes everything
Flavor Name: Espresso, Size: 35.2 Ounce (Pack of 1)
I've gone through more bags of this than I can count — it's become my default espresso bean and I don't see that changing.
I grind it fresh for espresso and the difference vs. pre-ground is immediately noticeable — more crema, better aroma, cleaner taste. If you're still buying pre-ground, this is a good reason to stop.
Flavor-wise it's smooth and approachable — medium roast means no harsh bitterness, no aggressive dark-roast smokiness. Just clean, well-balanced espresso. The 100% Arabica shows; it doesn't have that robusta edginess you get in cheaper blends.
The 2.2lb bag is good value compared to buying smaller bags or anything from a specialty roaster. For everyday home espresso, the price-to-quality ratio is hard to beat.
Only mild gripe: the bag isn't the most resealable after the first open — I transfer mine to an airtight container. Minor inconvenience for a bean this good.

New Favorite Coffee
Flavor Name: Espresso, Size: 35.2 Ounce (Pack of 1), Flavor Name: Espresso, Size: 35.2 Ounce (Pack of 1)
Let me start out by saying I am a coffee fiend. I drink it all hours of the night and day and I've tried just about every brand you can think of. I took a chance ordering this and I'm so glad I did! Reading the other reviews helped me so I hope this helps someone else, too.
No one is paying me for my opinion, I'm not getting a single thing for writing this except the satisfaction of reporting on a quality product.
Not only is it a good price for how much you get, (09/25- $22 for 35.2 oz) but this is some of the smoothest coffee I've ever tasted. The beans are so shiny and just pretty. They're not all dried out and dull and dessicated looking like some coffees... The beans smell so good in the bag and even better once I've ground them. They grind up very quickly and easily too. There's no bitter aftertaste. Just pure, delightful, delicious coffee.
I got the 5/10 espresso, and it's perfect for me. it's just strong enough. I like medium-strong roasts, so if you prefer darker or lighter roasts they have plenty of other options.
I use both a drip coffee pot and a French press and this works beautifully in both. The crema in the French press is gorgeous.
It's so far above other brands- even Seattle's best and eight o clock and Cameron's, which I thought I really liked... They don't hold a candle to this.
I can't wait to try the other flavors.

Good Beans for Home Espresso
Flavor Name: Espresso, Size: 35.2 Ounce (Pack of 1)
I’ve been using these beans daily for about two weeks in my espresso machine, and they’ve been really consistent. The flavor is smooth and easy to drink, with a mild nutty note and low acidity. It’s not overly bitter, which I personally like for everyday coffee.
One thing I noticed — you do need to dial in the grind a bit to get the best crema, but once you do, it comes out pretty nice.
On the downside, the aroma and intensity are a little on the lighter side. If you’re into strong, bold espresso, this might not hit that mark.
Overall, this is a great everyday option — especially if you want something smooth and reliable without too much bitterness. Good value for the size too.

Great Gum to Help with Health Journey
Flavor Name: Spearmint, Size: 55 Count (Pack of 1)
This PUR Spearmint gum gets five stars from me. The spearmint flavor is really good and refreshing, but the only downside is the flavor doesn’t last super long compared to regular gum. Still, I bought this more for the cleaner ingredients than anything else since it fits into my current health journey and I wanted something aspartame-free.
The gum has a little outer shell coating on it, but it’s still soft and easy to chew. It’s not hard or weirdly crunchy or anything like that. The family-size bag is also nice because it’s easy to throw in your car, backpack, or wherever without taking up a ton of space. Plus the resealable zipper bag helps keep it fresh.
If you’re trying to avoid a bunch of chemicals and want a cleaner chewing gum option, this is definitely worth trying. I’d buy it again.

Good product
Flavor Name: Spearmint, Size: 55 Count (Pack of 1)
Very soft and chewy, sugar free and has good flavor. It does lose its flavor around 10 minutes in but that's how long its meant to be chewed for anyway.
