Saru48W+ rev1

My third keyboard designed from scratch, this time with Bluetooth connectivity.

I wanted a more compact portable keyboard with Bluetooth connectivity and an encoder.

Different MCU, different firmware.

Components:

• 1x nice!nano (ZMK), USB-C and Bluetooth
• 1x 3.7V 503040 600mAh LiPo battery
• 48x switches
• 1x EC11 encoder
• 30x M2 5~6mm screws
• 6x M2 nuts
• 12x M2 10mm stand-offs
• 2x M4 Low profile brass heat inserts
• 2x M4 6~8mm Socket cap head screws
• 1x micro switch (power)
• 1x micro push button (bootsel, reset)
• 3D printed case, plate, feet
