This board has a 15 pin D-Sub socket port, that you can plug any classic PC joystick into. Onboard is a ATtiny816 helper chip that acts as a I2C peripheral using our 'seesaw' library. Two STEMMA QT ports mean you can plug this board in using a 4-pin JST SH cable to any microcontroller or microcomputer with I2C support and read the joystick X & Y plus the two buttons, even if your main chip doesn't have analog inputs. There's even a 5V power generator on-board since joysticks are expecting that voltage.

The RP2040 is a powerful chip, which has the clock speed of our M4 (SAMD51), and two cores that are equivalent to our M0 (SAMD21). Since it is an M0 chip, it does not have a floating point unit or DSP hardware support - so if you're doing something with heavy floating-point math, it will be done in software and thus not as fast as an M4. For many other computational tasks, you'll get close-to-M4 speeds!

The MCP4728 lets you chose between two sources for your reference voltage: the input voltage that you use to power it on the VCC pin, or an internal 2.048V reference voltage. If you use the internal reference voltage (Vref in DAC speak) you can choose between 1X or 2X gain for the output, allowing your voltages to range from 0V to 2.048 or 0V to 4.096V as your application requires.

This chip has twice the flash, and four times the SRAM of its earlier sibling, the nRF52832 - 1 MB of FLASH and 256KB of SRAM. Compared to the nRF51, this board has 4-8 times more of everything. For this chip, we've added Arduino IDE support - you can program the nRF52840 chip directly to take full advantage of the Cortex-M4 processor, and then calling into the Nordic SoftDevice radio stack when you need to communicate over BLE. Since the underlying API and peripherals are the same for the '832 and '840, you can supercharge your older nRF52832 projects with the same exact code, with a single recompile!
