This repository contains the hardware design files (eagle) and the firmware (Arduino) for the Fablab Winti RFID machine access controller.

• Based on ESP8266 so it has direct access to WiFi
• RFID reader
• OLED display
• Piezo buzzer
• Multi-color LED
• SD card for event logging
• RTC for accurate time keeping without network access
• Isolated output with screw terminal
  • Option 1: Relay output: 250V, 5A, NC or NO with a 5x20mm fuse
  • Option 2: Opto-coupled output (50V, 40mA)
• Input voltage: 5V ±0.5V with input protection (reverse voltage protection, overvoltage protection)
• Three input connecters: 5.5x2.1mm DC jack, Micro USB jack, screw termianl

• Easy web based configuration
• Time sync through NTP
• Automatic synchronization of local RTC
• Automatic update of user database from server
• Local storage of access rights: works during network failures
• Local data logging to SD-Card or Flash (TBD)
• Transmit log data to server as soon as it is available
