ATTiny13/13A/25/45/85 Push Button ON/OFF Controller

Ultra-Low Power Single push button ON/OFF controller based on ATTiny13/13A/25/45/85 for other MicroController and circuits application.

Simple mode features:

• Ultra-Low Power 000.2uA (200nA)
• Supported uControllers: ATTiny13/13A/25/45/85
• Single push button ON/OFF

Advanced mode features:

• Ultra-Low Power 000.2uA (200nA)
• Supported uControllers: ATTiny13/13A/25/45/85
• Hold down button to ON/OFF
• External Shut down signal from other Micro-controllers or circuits

Note

Please upload the bootloader first, then upload the code.
