That\'s an option. The circuit is pretty simple!

yeh, looks like a few holes and an outline, wouldn\'t take more than a few minutes

We\'ll do a PCB, with proper plated holes, silk, solder mask, all that.
The layout is done!
My contract layout guy suggests sierra circuits or rushpcb or
sunstone. We\'ll get quotes for 30 or so.

if you want to nitpick, you should move one of the wires to the other end
of the board so all the caps have the same trace length and share current

Either Sunstone or Advanced Circuits is fine for domestic quick-turn work..
Or WellPCB for those with finite budgets who can wait a week or two.
I prefer Advanced Circuits over Sunstone these days because Sunstone\'s
silkscreen capabilities are stuck in the Fahnestock-clip era.

This is our first use of an ST Arm, which we are using now that the
NXP parts seem to be going EOL. I hate when people do that, dump on
their customers.

Which ones are going away? We use a lot of LPC845s and LPC804s, and are
looking at using one of the NXP M4F/M0+ parts.
The ST factory headers are hideous. What toolchain are you folks using
with the ST parts?

The ST is nice in some ways. It\'s very versatile about pin assignments
and has lots of goodies on chip. As usual in uPs, the ADC is pretty
bad.

LPC3250, and I think some of the 1768 series.

I\'ll ask Paul the next time he\'s in. He has said some baddish stuff
about their libraries. But first time on a new CPU, things happen.
He wrote a boot loader that we jtag into the STM32F207IGT6. We might
eventually have a distributor do that. At powerup, the boot reads a
plug-in serial flash chip that has the specific runtime code and the
FPGA image.
We can email upgrade files to a customer, or we can send him a new
physical flash plugin thing, so one of his techs can just replace it.

I\'d like to move more to ZYNQs and PicoZeds for anything that has an
FPGA or DRAM. PicoZed is slick. I should have used that on my
alternator box.

We do something similar--Simon wrote a bootloader that can flash the 845
over half-duplex MODBUS, which is pretty slick. The stock BL can do it
over full-duplex UART, SPI, or SWD. We\'re using it in the sensors in my
\"connectors for high vibration\" thread.

The STM build in bootloader can flash from UART/USB/I2C/SPI/CAN
In half-duplex? That\'s the parlour trick.
