Butterfly PCB

Description

Description Videos Show Reviews Allows two HAT or pHAT (or a mix) to be attached to a single Raspberry Pi 40-pin header. All pins are connected*except*ID_SD and ID_SC (HAT EEPROM), which have solder jumpers this allows HATs which follow the specification correctly to operate without a conflict on the EEPROM. The EEPROM on the primary HAT (over the Pi) is always connected to the Pi, and if the solder jumpers are bridged, theID_SD and ID_SC signals are connected to both primary and secondary HAT (for use when only the HAT/pHAT in the secondary connector has an EEPROM). When not using the EEPROM you may need to manually configure the Pi for your HAT. Before ordering/using multiple HATs, you*MUST*check for conflicts for example, enable/select pins when using SPI, I2C addresses, and GPIO pin conflicts and modes. We would advise checking on Pinout.xyz and/or with the HAT seller for used pins/modes in use. The Butterfly board would normally be used with the Male + Long Female headers (Long Female for the Pi + primary HAT and Male for the secondary HAT). This item is the bare Butterfly board only. Header pins and standoffs must be purchased separately. Soldering Tips The top side of the board is indicated by the white line in between the connectors (also has a white line next to pin 1 on both square GPIO pads), we advise soldering the Long Female header first; otherwise accessing the pins is difficult. Long Female pins should be inserted from the bottom of the PCB and be soldered on the top of the board(use holes nearest the Butterfly text on the top side). Maleheaders should be inserted from the top of the board and soldered on the bottom (use holes nearest the 8086 logo on the top side of the board).
