MICROCHIP ATMEGA168-20PU 8 Bit Microcontroller, ATmega, 20 MHz, 16 KB, 1 KB, 28 Pins, DIPThe ATMEGA168 20PU is a 8 bit high performance, low power AVR RISC based Microcontroller Unit combines 16kB ISP flash memory, 1kB SRAM, 512B EEPROM, an 8 channel 10 bit A D converter (TQFP and QFN MLF) and debugWIRE for on chip debugging. The device supports a throughput of 20 MIPS at 20MHz and operates between 2. 7 to 5. 5V. The current consumption is a function of several factors such as operating voltage, operating frequency, loading of I O pins,
The ATMEGA168-20PU is a 8-bit high-performance, low-power AVR RISC-based Microcontroller Unit combines 16kB ISP flash memory, 1kB SRAM, 512B EEPROM, an 8-channel/10-bit A/D converter (TQFP and QFN/MLF) and debugWIRE for on-chip debugging. The device supports a throughput of 20 MIPS at 20MHz and operates between 2.7 to 5.5V. The current consumption is a function of several factors such as operating voltage, operating frequency, loading of I/O pins, switching rate of I/O pins, code executed and ambient temperature. The dominating factors are operating voltage and frequency. The difference between current consumption in power-down mode with watchdog timer enabled and power-down mode with watchdog timer disabled represents the differential current drawn by the watchdog timer.

The Perfect Firm Pillow l
Size: Queen (1 Count), Color: Original White (Cooling)
It is everything it claims to be, cool, comfortable and strong. I got this for my husband first, he loves it and then got one for my son, he uses it to support his knees and has been sleeping much better since then.
They both needed a firm pillow that is not super soft, firm but not achy.
Finally found the perfect one.

Soft,comfortable and great quality!
Size: 26 x 26 inches, Style: 2 Pack
I’m very happy with these pillows! They are soft, comfortable, and provide great support without being too firm or too flat. I also appreciate that they’re hypoallergenic, which is a huge plus. They fluffed up nicely and have held their shape well after use. Great quality for the price and they made a noticeable difference in comfort. Definitely recommend!

Good pillow, not the best overall but it's good value for what you pay.
Size: 20 in x 54 in, Style: 1 Pack
Can be slightly uncomfortable at first, but it goes away quickly, very soft and doesn't hold shape very well, but pillowcases fit well on it, it's pretty quality, and it's durable. There's not much more you can ask for in a pillow.
