The Challenger RP2040 WiFi is a small embedded computer equipped with a WiFi module, in the popular Adafruit Feather form factor. It is based on an RP2040 microcontroller chip from the Raspberry Pi Foundation which is a dual-core Cortex-M0 that can run on a clock up to 133 MHz. The RP2040 is paired with a 8 MB high-speed flash capable of supplying data up to the max speed. The flash memory can be used both to store instructions for the microcontroller as well as data in a file system and having a file system available makes it easy to store data in a structured and easy to program approach. The device can be powered from a Lithium Polymer battery connected through a standard 2.0 mm connector on the side of the board. An internal battery charging circuit allows you to charge your battery safely and quickly. The device is shipped with a programming resistor that sets the charging current to 250 mA. This resistor can be exchanged by the user to either increase or decrease the charging current, depending on the battery that is being used. The WiFi section on this board is based on the Espressif ESP8285 chip which basically is a ESP8266 with 1 MB flash memory integrated onto the chip making it a complete WiFi only requiring very few external components. The ESP8285 is connected to the microcontroller using a UART channel and the operation is controlled using a set of standardized AT-commands.

The mikroBUS standard was developed by MikroElektronika. Similar to Qwiic and MicroMod interfaces, the mikroBUS socket provides a standardized connection for add-on Click boards to be attached to a development board and is comprised of a pair of 8-pin female headers with a standardized pin configuration. The pins consist of three groups of communications pins (SPI, UART and I²C), six additional pins (PWM, Interrupt, Analog input, Reset and Chip select), and two power groups (3.3 V and 5 V). The RP2040 is supported with both C/C++ and MicroPython cross-platform development environments, including easy access to runtime debugging.

The Tabloid/A3 size Magnetic Easel is a sturdy work-holding tool that provides an alternative method of positioning paper or other workpieces for use with the AxiDraw V3/A3 and AxiDraw SE/A3. A heavy-duty alternative to the regular A3 clip easel, it can be used with binder clips or the (included) positioning rulers, magnets, and magnetic spring clips. The base of the easel is a heavy-gauge sheet of magnetic steel. It has a powder-coat finish, lightly textured to help hold paper in place and light gray in color for visible contrast against most types of paper. Rubber bumpers on the bottom side (along with the substantial weight of the steel) ensure a no-slip grip on your work table. To help index your paper in a consistent and reproducible position, the easel includes two six-inch (15 cm) rulers that you can rest your paper up against. The rulers are easy to remove and reversible, with inch and centimeter markings on the two sides. They can also be removed completely if you like, leaving just a flat sheet of steel (with a few ruler-mounting holes in it). This A3 easel also includes a special set of paper holding clips and magnets: Two special spring clips with magnetic bases, plus six skinny magnets for holding down paper. The two special spring clips each have two curved tines that apply gentle pressure to your paper. They allow you to slide paper directly in and out, quickly and easily, without touching any magnets, clips, or tape. They have a long reach to be positioned behind the rulers, or elsewhere if you prefer. Magnetic bases allow you to position them where needed. Two of these spring clips provide just enough pressure to keep a sheet of paper steady while you write or draw on it. This set also includes six cylindrical magnets, 4 mm in diameter and 10 mm tall, which are easy to position and firmly hold paper. The tall aspect ratio makes them particularly easy to grasp (unlike disc magnets). Perhaps more importantly, they tend to yield and tip over if hit by an errant pen tip, rather than holding so fast as to damage your pen or move your paper. Overall dimensions: 18.12 x 12.72' (46.0 x 32.3 cm) Suitable for use with A3 and US Tabloid/Ledger paper sizes, envelopes, two sheets of Letter or A4 paper, or smaller sizes of paper.
