About the NanoDD PCB

NanoDD is an open source TI MSP430/CC PCB design by LithosphereRocketry, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 37.9 × 10.2 mm, with 32 components from 15 distinct parts.

Its main chip is the MSP430G2452IRSA16, from the TI MSP430/CC family. Other key parts include the GZP6816D, ZD24C128A-XGMB and XC6206PxxxMR. By type, the board carries 15 resistors, 5 capacitors, 4 ICs, 3 connectors, 2 transistors and 1 battery holder.

It belongs with the dev boards & breakouts designs in this gallery.

From the project

A very small dual-deployment altimeter for low- and mid-power rockets.

Firmware for NanoDeploy is located in the firmware directory. Most day-to-day operations are handled by that folder's Makefile.

The setup process for TI's MSP430 toolchain is pretty miserable on modern Linux. See firmware/install-notes.md for details.

Run make run to upload the code to an attached MSP430 development board.

Run make gdb to upload the code to the attached dev board and start a GDB server session. From a separate terminal, then run msp430-gdb. (The included .gdbinit file should take care of all the necessary setup.)

NanoDD: common questions

What microcontroller does the NanoDD use?

The NanoDD is built around the MSP430G2452IRSA16, from the TI MSP430/CC family.

How big is the NanoDD PCB?

The NanoDD measures 37.9 × 10.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the NanoDD?

32 components, from 15 distinct parts. The full bill of materials is listed on this page.

Where can I download the NanoDD design files?

From the LithosphereRocketry/NanoDeploy repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the NanoDD design in my own project?

Yes, under the terms of its GPL-3.0 license, which LithosphereRocketry chose for the repository.

Can I test firmware for the NanoDD without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug TI MSP430/CC firmware against it before you order a PCB.
