With the SY120 StarterKit it is possible to evaluate the platform in real environment. The StarterKit PCB is equipped with:
The complete StarterKit system consists of:
The system can be powered by M8 connector (24V nominal) or direct on the PCB via microUSB.
The M8 4-pin female connector is used to power the sensor.
The connector has 4 pins. Only 2 Pins are used to to power the device:
The RJ45 is a standard industrial 10/100/1000BaseT connector.
The on-board micro USB is used for debugging and powering of the board during development. The USB is connected to UART0 (Kernel Logs) via FTDI Virtual COM Bridge.
The microSD card inteface is connected to Ganymed Port SPI5.
To use the JTAG interface, following devices are needed:
The SENSRY-JTAG-20-10 adapter can be purchased from Sensry. The JTAG port is a 10-pin 1.27mm (0.5”) pin header and fits to the SENSRY-JTAG-20-10 adapter.
The port is a 10-pin 1.27mm (0.5”) pin header. The header is used to program the firmware (AT-command set) of the ESP32 if nescessary.
The port is a 12-pin 1.27mm (0.5”) pin header to use for external sensors and periphery. The voltage level for all ports is 1.8V. It includes one SPI, one I2C and two GPIOs.
The port is a 12-pin 1.27mm (0.5”) pin header to use for external sensors and periphery. The voltage level for all ports is 1.8V. It includes two I2S interfaces and two GPIOs.
The PCB is equipped with two MEMS microphone sensors and a vibrations sensor.
The two ICS-43434 are connected as stereo to the I2S Port 0.
The vibration sensor MIS2DH is connected to I2C Port 1. The two interrupt pins are connected to GPIO13 and GPIO14.
The board contains a reset switch, a user LED (LED1)connected to GPIO10.
Additionally, there is a power indicator LED for 5V (LED2) and 3.3V (LED3)
