A list of the basic electronic components we use in our lab.Most of them come from DigiKey. See also our electronics kits and tools page for more information about the materials and tools in our electronics lab. Also, check out the Adafruit parts wiki and the Fab Lab inventory for more parts.
Batteries
CR2032: coin cell battery (3V, 20mm diameter). Also available from Sparkfun.
Rechargeable Li-Po batteries (3.7V) from SparkFun: 20 mAh, 110 mAh, 850 mAh, 1000 mAh (pictured), 2000 mAh, 6000 mAh (6 Ah)
Sewable Electronic Components
sewable batter holder (CR2032). Also available from SparkFun.
ATtiny45V: through hole, surface mount (SOIC-8)
ATtiny85V: through hole, surface mount (SOIC-8)
ATtiny84: surface mount (SOIC-14)
ATmega168: through hole, surface mount (TQFP-32)
ATmega328P: through hole [ DK, SF ], surface mount (TQFP-32) [ DK, SF ]
Note that other variations (e.g. ATmega168V or the ATmega328) may be hardware compatible, but aren’t supported by the Arduino software (and may be time-consuming to get set up).
