**PLEASE READ ENTIRE DESCRIPTION**

The nice!nano is a wireless, BLE (Bluetooth) enabled replacement for the Pro Micro or Elite-C powered by the nRF52840 SoC. The nice!nano utilizes a LiPo battery allowing you to make your board completely wireless and has an on-board charging circuit, so simply plug in your keyboard to charge the battery, and use it wireless any other time you want.

**Note:** Includes square post headers for assembly. It is recommended to socket using Mill Max Low Profile Sockets.

**Note:** Due to the nature of this product, it cannot be included in assembly orders.

**Note:** Please remember, you will need to find space on your keyboard to put the battery. The stock header pins allow the battery to rest underneath the controller, but do remember that it is recommended these be socketed, so check your clearances depending on the socket you use (if you elect to use a socket).

**DISCLAIMER:**

For advanced users only! Know what you are getting into please -- this is NOT a drop-in replacement and is not 'plug and play.' You will likely have to do extensive setup and have programming knowledge in order to use this product and make your board Bluetooth. Boardsource does not guarantee a smooth implementation and we are not necessarily able to extensively help you get the nice!nano v1.0 working on your build. The nice!nano documentation [can be found here](https://docs.nicekeyboards.com/#/nice!nano/).

Compared to existing wired solutions like the Pro Micro or Elite-C, the nice!nano v2.0 is still in development, and along with that comes a certain amount of hands-on setup, troubleshooting, and general knowledge that is required in order to successfully install. As a result, this product is not recommended for beginners and other microcontrollers should be chosen instead.

Due to running on 3.3v compared to the 5v that the Pro Micro and Elite-C supply, it is not recommended to install RGB LEDs or OLEDs as these account for considerable power-draw.

nice!nano v2.0

The Elite-C is an Pro Micro drop-in Microcontroller developed to offer a better alternative to the Pro Micro while still being fully backwards-compatible. It sports the very same AVR ATmega32u4 8-bit microcontroller which has an integrated USB controller and pin-out while adding 6 more pins. Like the name states, the Elite-C features a more modern USB-C port which is also more durable and less prone to tear-out. Since almost all keyboards utilize the Pro Micro's footprint, this drop-in upgrade is a great way to take any board you build to the next level. 

The newest iteration, the Elite-C v4, features a 'low-pro' design and is the new standard for the Elite-C. Not only is the v4 shorter in height that the previous version, it is more durable. The center-mount USB C connector is considerably more sturdy and also decreases the total height of the Microcontroller. Another new addition is the inclusion of a VBUS pin that is broken out and placed directly above pin B0 on the PCB.

the fr4 on this batch is 2mm instead of 1.6mm no real change to usability.

**Introducing the Blok by Boardsource, an RP2040 (ARM) based controller built for the keyboard community.**

Blok’s elevate any keyboard compatible with Pro Micro Footprints and grants them instant access to a modern and feature-rich ecosystem. Users who don’t want to touch a text editor or config file don’t have to, Blok’s work out of the box with Peg. Users can map keys, set LED colors,  configure rotary encoders, create OLED images, and much more all from within an easy to use visual program (GUI). Many of Peg’s features and configuration options are unavailable through any other flashing program built for yesterday’s ATmega32U4 processors. Now,  deep configuration and rich features custom keyboards offer can be configured easily instead of becoming another project. On the other hand, users who enjoy in-the-editor programming, product development,  design, or any other roll your solution will similarly love the Blok. Shipping with KMK and CircuitPython out of the box, Blok’s offer enthusiasts and creators a modern development environment limited only by your imagination instead of programming knowledge and hardware constraints. Create your entire keymap in Python within a single main.py file and test your changes instantly, no recompiling necessary.  Remember, if this isn’t your thing — Peg can handle it for you. 

Built on top of a powerful RP2040 ARM microprocessor and designed with the future in mind, Blok’s handle whatever you throw at them.  Compared to older ATmega based controllers Blok’s have an incredible 100x the RAM, 8x the computing speed, 500x the ROM, are 32 bit instead of 8 bit, and are dual-core instead of single core. These are huge upgrades and allows for innovation and development within the custom keyboard space.  Blok’s offer additional features and functionality compared to other RP2040 based controllers as well,  such as OLED screen compatibility, innovative reset/boot switches accessible in any controller orientation, USB-C connectivity and a programmable RGB LED on-board.
