Page 21: System Integration
The Bitsy has an on-board switching power supply which regulates from input voltage ranges between 5-12V. The input to this supply can come from Bitsy pins DC_IN or VBATT to support dual supply inputs. Should the unit be required to operate from a single supply, it is recommended to utilize the VBATT input. -
Page 22: Mechanical Specifications
Bitsy User’s Manual The Bitsy supply outputs 5V, +3.3V, 30V (LCD VEE), and 1.75V (CPU Core). It is possible to regulate these voltages externally, and supply them through connector pins. See section 4.3 for more information. 4.2 Mechanical Specifications The Bitsy is 3 by 5 inches in size. This section describes the component dimensions and mounting of the board. -
