Info:
1) A 0-ohm resistor has been soldered to connect the VCC_MUX pin to the mikroBUS socket. If an add-on
module cannot handle 5V on this pin, the 0-ohm resistor has to be removed. For more information, see

4.4.3 WINC1510 Wi-Fi
Microchip's WINC1510 is a low-power consumption 802.11 b/g/n IoT module, specifically optimized for low-power IoT
applications. The module integrates 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
(21.7x14.7x2.1 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.
WINC1510 provides internal Flash memory as well as multiple peripheral interfaces, including UART and SPI. The
only external clock source needed for WINC1510 is the built-in, high-speed crystal or oscillator (26 MHz). WINC1510
is available in a QFN package or as a certified module.
The communication interface between the ATmega4808 and the WINC1510 Wi-Fi module is SPI, together with some
enable signals and interrupt. The rest of the connections are left unconnected.
