10 Reference Design

This section provides the reference schematic for the ATWILC1000-MR110xB module with SPI and SDIO host interfaces.
Figure 10-1. Reference Schematic - SDIO Host Interface
Note:
  1. Add 10 uF and 0.01 uF decoupling capacitors very close to pin 24 (1P3V_TP) and GND.
  2. Add test points for pins 2, 3, 25 and 27.
