Originally envisioned for environmental data collection, the Mini Logger can be useful for any application requiring remote data collecting. 

​

Features Include:

 

• Small Form Factor, 1.00” x 1.20” (25.4mm x 30.48mm)

• Propeller Core Microcontroller

• DS3232 Temperature compensated Real Time Clock with battery backup.

• 24LC512 64K EEPROM.

• TMP102 I2C Temperature Sensor

• Wide operating range, 4v – 16v

• FPF2106 Load switch with over current/over temperature fault flag. Power off peripherals when not being used.

• Diode protected power input to prevent damage from wire reversal.

• +3.3v Regulator with over current and over temperature protection.

• Crystalless operation up to 48MHz. 

• ADS1115 2 Diff. /4 Single Channel 16 bit Analog to Digital Converter with +2.5v Sense reference and 220Ω current limiting resistors.

• FT230XS USB to UART for direct connection to a pc via USB connection for programming and communication.

• S25FL512S 64M x 8 Flash Memory. Record data for 18 months or more. Time depending on logging frequency and data size.
