Programming tool that can provide power to the target for quicker programming of production units

[LLuna.1]

We have the task to enable an assambler to quicker his assambling process of a couple of hundreads of units, and one of the time consuming process is to attach batteries, program the unit and then deatach the batteries for the later steps of assambling the enclousure.

So I am looking for a programmer/debugger that can provide power to the device to program it. Currently we use the STLink-v3Mini to program it (which seems cannot provide power to the MCU), the targets are STM32L412 and STM32L4A6, we would be using STM tools to program the units, so programmers compatible are the ones we are looking for.

All suggestions are appreciated!

Original ST-LINK/V2 and J-LINK's typically push 5V via Pin 19 of ARM 20-pin JTAG connector

Depends on voltage/current demands of your board.

Perhaps bed-of-nails or Tag-Connect ?

Card edge connector, castelations, or break-off PCB section.

Use an interposer to get power onto a connector ?

Find an engineer with some imagination ?

We have used SEGGER Flasher Arm: https://www.segger.com/products/production/flasher/models/about-flasher-arm/

It can provide 5 volts @ 400 mA.
