@docbrown can you explain the function of J1

docbrown

J1 is a pin header (01x06, 2.54mm vertical) connector that provides easy connection points for external devices or testing. Pins on this connector are: Pin_4, Pin_5, Pin_2, Pin_3, Pin_1, and Pin_6. The purposes of these pins are: Pin_1 is connected to the -6V net, Pin_2 to Ground, Pin_3 is connected to the gamma radiation signal (GAMMA_RAW), Pin_4 is used for the RAD_BEEP signal, Pin_5 connects to the +3.3V power supply, and Pin_6 connects to the +6V net.

@docbrown is IC1 wired correctly?

docbrown

Yes, IC1 (DS3231M+) appears to be wired correctly. The VCC and VBAT pins are connected to the 3.3V power supply, GND is connected to the ground, SDA and SCL are connected to the appropriate microcontroller pins (U3:PB11 and U3:PB10 respectively), and the ~RST pin is connected to the microcontroller's PA13 pin for control. This should allow for proper operation of the real-time clock.

As an AI, I do not have real-time pricing information, but I can help you find the cost of the capacitor you mentioned (C3), which has a capacitance of 10nF and is a non-polarized capacitor in an SMD_0603_1608Metric package.
To find the cost, you can visit electronics component distributor websites like Digi-Key, Mouser, or RS Components, and search for capacitors with the given specifications.
Keep in mind that pricing may vary depending on factors such as brand, quantity ordered, and available discounts.
