Adafruit METRO 328 with Headers - ATmega328 updated 11-24 Wire strippers - We've upgraded

Wire strippers - We've upgraded our basic 'adjustable' wire strippers to these multi-sized wire strippers

Optional: high-bandwidth output transformer provides full galvanic isolation of the electrical output (not in the standard version)

Many lower cost solenoids are only push type or only pull type and may not have a captive armature (it'll fall out

Adafruit METRO 328 with Headers - ATmega328 updated 11-24 Wire strippers - We've upgradedAdafruit sure loves the ATmega328, they use them a lot for their own projects. The processor has plenty of GPIO, Analog inputs, hardware UART SPI and I2C, timers and PWM galore just enough for most simple projects. When they need to go small, they use a Pro Trinket 3V or 5V, but when size isn't as much of a concern, and an USB serial converter is required, we reach for an Adafruit METRO. This is the Adafruit METRO with headers. It comes with headers
