+Starts up the Pico W and has it listen on port 1234
+
+Any TCP request will be responded to with 4 `u16`(16 bytes) adc raw reads in the order:
+
+1. Internal Temp Sensor
+2. GPIO 26
+3. GPIO 27
+4. GPIO 28
+
+While this can be configured with any external hardware, the current setup is:
+
+- LM4040 3V ref across `ADC_VREF` and `GND`
+- GPIO 28 is tied to GND
+- GPIO 27 is tied to 3V
+- GPIO 26 is read via a voltage divider of 22.3k / 3.3k
