All vital components (processor, clock source, memory, power regulator) are provided on the BS1's tiny PCB; just connect power and go! The BASIC Stamp 1 (BS1-IC) is an ideal fit for applications that don't require the speed, I/O, and memory of the BASIC Stamp 2 series of microcontrollers.PC In5-volt DC input/outputReset input/outputGeneral-purpose I/O pins: each can sink 25 mA and source 20 mA.General-purpose I/O pins: each can sink 25 mA and source 20 mA.General-purpose I/O pins: each can sink 25 mA and source 20 mA.General-purpose I/O pins: each can sink 25 mA and source 20 mA.General-purpose I/O pins: each can sink 25 mA and source 20 mA.General-purpose I/O pins: each can sink 25 mA and source 20 mA.General-purpose I/O pins: each can sink 25 mA and source 20 mA.Unregulated power in: accepts 5.5 - 15 VDC (6-40 VDC on BS1-IC rev. b).System groundGeneral-purpose I/O pins: each can sink 25 mA and source 20 mA.PC Out
