2.9.3 A/D Conversion Bypass Capacitors
There is a foot pattern on the M3028BT-EPBM board for mounting bypass capacitors for an A/D conversion circuit near the
MCU. Mount suitable bypass capacitors as occasion demands. Figure 2.22 shows where they are installed and the
configuration of this product.

IMPORTANT
Note on the A/D Converter Function:
z
Because a package converter board and other devices are used between the evaluation MCU and the user
system, the A/D converter operates differently from that of an actual MCU. Make the final evaluation of the
A/D converter with an actual MCU.
