Nice!Nano FAQ

⚠️ Recommended Soldering Iron Temperature when soldering is 240 Celsius (464 Fahrenheit).
Controllers are heat sensible and fragile components, please handle with care.

⚠️When soldering the nice!nano, avoid using high iron temperatures or irons without temperature control, as you could damage the main nRF52840 chip. A temperature around 270°C-300°C should be hot enough. The higher the temperature, the more likely you are to damage the board.⚠️

Nice!Nano is a replacement for the popular Pro Micro controller and made to turn your keyboard wireless using ZMK software.
Flashing nice!nano is as easy as a drag and drop.

If you plan a wireless build and to hotswap the controller on a split keyboard you’ll need:
2x Li-Po Battery and 2x Low Profile Controller Sockets and 2x Mill Max Socket Pins:

📣 Can i use Nice!Nano wired with USB-C cable and TRRS, without any battery ?
Yes, you can. You can use a split keyboard with nice!nano wired, having a battery soldered to nice!nano or not. Works in both cases.
📣 How much does it take to charge the 110mah Rechargeable Li-Po Battery with Nice!Nano ?
It takes about 2 hours to fully charge the 110mah Rechargeable Li-Po Battery.
Battery charging time ( hours ) = Battery capacity ( in Ah ) / Current supplied ( in A )
Li-Po Battery capacity: 110 mAh = 0.11 Ah
Current Supplied by nice!nano = 100 mA = 0.1 A
110 mAh Battery charging time = 1.1 Hours = 0.11 Ah / 0.1 A
📣 How much the 110mah Rechargeable Li-Po Battery using with Nice!Nano will last without having to recharge ?
Depends on many factors and variables, but on average, in my experience, master side lasts about 5-7 days using it around 8h/day without having to recharge (slave half lasts more time than master’s). Here is the ZMK Power Profiler. You can simulate and have an idea of the battery autonomy.
After 15 minutes of inactivity the keyboard goes into deep sleep mode, saving efficiently battery charge. The power draw on nice!nano v2 during deep sleep is around 20uA, which is about 1mAh every 2 days. The battery on slave side will last more time than on the master side, as it consumes less energy.
📣 Can i use my keyboard wired while it is charging the 110mah Rechargeable Li-Po Battery ?
Yes, you can.
📣 What is the difference between Pro Micro Controller and Nice!Nano Controller ?
• Pro Micro is cheaper, works only wired and supports QMK Firmware.
• Nice!Nano works wired and/or wirelessly. Requires 3.7v Li-Po battery for wireless mode. Supports ZMK Firmware.
📣 I have no idea how to code. Is there any easier way to change my keymap ?
There is an easier way to change your keymap.
ZMK Keymap Editor by nickcoutsos. You still need to have a general idea on how to work with terminal, github and some code. I haven’t tried it so can’t say much about it, but i have seen people using it so it works.
