Appendix B Fanout board (MB1280)
The fanout board, shown in Figure 29, is included in the STM32H7B3I-DK Discovery kit. It can be connected to
P1 STMod+ connector and it provides access to:
• MikroElektronika Click board compatible connectors (MB1280 CN10 and CN11: two 1x8-pin female
connectors)
• ESP-01 compatible connector (MB1280 CN4: 2x4-pin female connector)
• Seeed Studio™ Grove compatible connectors (MB1280 CN3 and CN2: two 1x4-pin male connectors)
• Reserved standard 2.54 mm pitch of STMod+ pin header for breadboard
The main active component for this fanout board is the 3.3 V regulator MB1280-U1 (200 mA).
