PCF2131-ARD

PCF2131-ARD is a PCF2131/PCA2131 Arduino® shield evaluation board. The PCF2131/PCA2131 is a CMOS real time clock (RTC) module and calendar with an integrated temperature compensated crystal (Xtal) oscillator (TCXO) and a 32.768 KHz quartz crystal optimized for very high accuracy and ultra low power consumption. PCF2131-ARD is used to evaluate the functions and performances of PCF2131/PCA2131. The evaluation board is intended to test and evaluate all characteristics of the silicon, such as I2C/SPI communication, power management, battery backup, timestamps, interrupts, and other internal features of the PCF2131 RTC.

• Equipped with Arduino Uno R3 port for direct connection with Arduino devices
• On-board header for direct connection to Aardvark I2C/SPI host adapter
• Adjustable power supply for complex tests and verification
• On-board battery holder for battery switch-over circuit test
• On-board jumpers for I2C-bus or SPI-bus selection
• On-board connector and switches for timestamp function tests
• Fully compliant with IMXRT1050 EVK board, including GUI (Windows 10)
• Compliant with i.MX Mini LPDDR4 EVK board, including GUI (Windows 10)
