This is an MC56F8006 Digital Signal Controller chip manufactured by Freescale. Around the chip, badge designer Joe Grand put test points that provide easy access to interfaces on the chip. Hackers can wire three of the testpoints to the three corresponding test points on other badges to create a multi-badge communications interface. Other test points provide access to a bootloader feature that allows for new code to be loaded onto the badge.
