-You will note in the above, that there is an additional small board being used. This board is not normally needed, it is a dedicated battery charging board I had on hand and was important before I had implemented putting the nRF52840 into it's "standby" state ( using <5μA ). The SPST on/off here connects between the charging board and the nRF52840 I use ((This arrangement allows for charging the battery with the board entirely disconnected and testing the nRF52840 when no battery is connected.)) can now be replaced with a momentary SPST connected as a reset switch. This reset will turn the nRF5280 on from standy. This state can be entered by a chord or triggered if idle for an hour((You can of course change the idle time or disable this timer.)) and off USB power.

-Also of note, the "Franken-Chorder"((Thanks for the name, Zach)) enclosure pictured is so named as it is made up from parts from several different enclosure attempts. The 3D printed [[3d_printer_files|flat bottom]](Zach & Nhat), some 3D printed keyswich holders(Zach), an [[3d_printer_files|acrylic top]] (Nhat).  Pictured with keyboard feet ((see parts list below)), mag connectors ((see parts list below)), Cherry MX switches, and mostly **very** old keycaps.

   * Optional: headers
   * Some form of enclosure or a 3D printed case and whatever hardware the case needs.
-  * Optional keybord legs, I like these which add some weight - [[https://www.amazon.com/dp/B0B4NML9CZ|Hagibis Laptop Stand Adjustable Height]]. These are pictured above.

   * Optional magnetic data and charging connectors. I prefer these as they eliminate the force of cable insertion and removal on the XIAO board. The ones pictured are [[ https://www.amazon.com/dp/B07MF9KWZR| N. NETDOT  Gen10]] I have also used the stronger and more expensive [[https://www.amazon.com/dp/B0D69KK6R2| 24Pin 240W Magnetic Right Angle USB C Adapter, 40Gbps Type]]
 There are a number of chords specific to this chorder. These do things like changing the HID mode between BLE and USB, put the board into the low power standby state, and blink system information on the chip's RGB LED.  My default for these chords are documented on the [[spiffchorder:modified_nasa:chart_function_keys|Function Keys - Function Mode Prefix]] chart.
