## notes

You need a segger jlink programmer to use this, USB dfu does not come with the initial bootloader of isp, and nrf52832 has no USB connectivity. nRF52840-dk development kit can be used, and also can double as a dongle for the trackers.

# slimenrfdock

dock test pcb

charging for 8 devices at 300mA, max power draw 2.4A

* Gets pretty hot if all 8 chargers are in use but it works fine
