great pcb design!
Where did you buy the DC-DC converter? Do you have a link?

3W DC-DC Boost Converter 3.3V-12V to ± 15V Output Step up Power Supply Module
Features:
100% Brand New and High Quality

±15V step-up module, 3W positive and negative output boost module, low 3.3VDC input, non-isolated DC-DC
Power modules, Can replace LM78XX / 79XX three-terminal regulator chip.

Wide voltage input: 3.3-13VDC
Boost Dual output: ±15V
Efficiency: 82%
Size: 23.5 * 14 * 6.3mm
Support single in-line or horizontal installation DIP
Conversion efficiency: 5V input, full 3W output, 82%
Ripple noise: 5V input, full 3W output, 60 ~ 120mV

Port definition:
VIN: 3.3V to 13V DC input
GND: Input Output Common GND
+Vo: Output Positive
-Vo: Output negative
NC: Vacant port, no electrical connection
En: Module enables:
VEN <0.8V, the module does not work;
1.4V <VEN <VIN or EN vacant when the module normal output.

NOTE: VEN <0.8V, the circuit configuration restrictions, +Vo Vin voltage output at this time still, but -Vo no voltage output.

Precautions:
1. The module does not support output short circuit protection board.
2. The output current is greater than 20mA can get a better product overall performance.
3. When -Vo overloaded, + Vo load is too light, it is recommended to increase the dummy load resistor between ground terminal and + Vo terminal.

Package Included:
1x ±15V Boost Power Module
