MCU. 1.8 Raspberry Pi compatible interface The EVK-ANNA-B112 includes a 40-pin IO header that can be used to interface with either a Raspberry Pi computer board or with a Raspberry Pi expansion board (HAT). The EVK-ANNA-B112 uses different hardware and software configurations depending on if it is connected to a Pi or a HAT;... - Page 15 EVK-ANNA-B112 - User Guide Figure 14 shows the layout of the Raspberry Pi interface and Table 10 explains the pinout in detail. There are three mounting holes that can be used for increased mechanical stability. The two on either side of connector J14 are common to all Raspberry Pi boards, but the third one is only compatible with the Pi Zero boards.
