ATmega4808

The ATmega4808 is a microcontroller featuring the 8-bit AVR
running at up to 20 MHz and with up to 48 KB Flash, 6 KB SRAM and 256 bytes of EEPROM in 28- and
32-pin packages. The series uses the latest Core Independent Peripherals (CIPs) with low-power
features, including event system, intelligent analog and advanced peripherals.

ATWINC1510

Microchip's WINC1510 is a low-power consumption 802.11 b/g/n IoT (Internet of Things) module,
specifically optimized for low-power IoT applications. The module integrates the following: Power
Amplifier (PA), Low-Noise Amplifier (LNA), switch, power management, and a printed antenna or a micro
co-ax (u.FL) connector for an external antenna, resulting in a small form factor (21.7 x 14.7 x 2.1 mm)
design. It is interoperable with various vendors' 802.11 b/g/n access points. This module provides SPI
ports to interface with a host controller. The WINC1510 provides internal Flash memory as well as
multiple peripheral interfaces, including UART and SPI. The only external clock source needed for the
WINC1510 is the built-in, high-speed crystal or oscillator (26 MHz). The WINC1510 is available in a QFN
package or as a certified module.
