[TangerineSDR] Teamspeak Call 07-15-2019 Meeting notes.

[Tom McDermott]

Notes from PSWS / TangerineSDR call of 07-15-2019
1. PMOD connector can be +3.3 or +5V provides SPI and I2C. Could be
where the Magnetometer and Extender plugs into.
PMOD connector information: <18:44:38> "Scotty WA2DFI W10":

2. Bill making good progress with higher performance using the Odroid N2.
Testing HDF5 writing to disk.

3. Dan is thinking about creating a 3D printed enclosure for the Tangerine
SDR system.

4. Two orange holes and two black holes are used for Odroid N2, Four orange
holes for Raspberry Pi. Some of the 6 can be used for mounting to the
chassis.

5.  "Dave W. KD0EAG": I ordered some differential I2C extenders based on
NXP’s PCA9615 IC from SparkFun for testing:
https://www.sparkfun.com/products/14589
<18:24:21> "Dave W. KD0EAG": I believe that I2C is pretty flexible for many
purposes
<18:41:02> "Dave W. KD0EAG":

<18:41:43> "Dave W. KD0EAG": That (above is the chip datasheet)

6. Tom will work on updates to the ICD and Specifications based on the
preliminary mechanical drawing, and start work on the RF module
Specification.

7. Rick to talk with John about potential oscillators for the Clock Module
that might meet the requirements, or variants for lower cost (PSWS) and
super high performance (not PSWS).
"Rick W2GPS": http://magicxtal.com/products/?S=18&C=99&I=308
MXO37/8D Low power high durable miniature OCXO.  10.0 MHz.
