- Alchitry Io Element Board
The Alchitry Io Element Board is the perfect way to get your feet wet with digital design. The Io features four 7-segment LEDs, five momentary push buttons, 24 basic LEDs, and 24 DIP switches that all lend themselves to fantastic beginner tutorials that will walk you through all the basics of FPGAs.
Alchitry Elements are expansion boards similar to shields for an Arduino or HATs for a Raspberry Pi but these are meant for your Au and Cu FPGA Development Boards. This Element is equipped with four connectors on the underside of the board that snap to an Au or Cu board. Be aware that the Io does not feature any connection points on the top of the board so you won't be able to stack any additional Elements on top of it.
On this most recent revision (v2) external pull up capabilities for the R12 resistor were removed
- 4x 7-segment LED digits
- 5x momentary push buttons
- 24x LEDs
- 24x DIP switches

Core Skill: Programming
If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.
Skill Level: Experienced - You will require a firm understanding of programming, the programming toolchain, and may have to make decisions on programming software or language. You may need to decipher a proprietary or specialized communication protocol. A logic analyzer might be necessary.

Core Skill: Electrical Prototyping
If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

everything arrived well and fast, but the I/O board some leds do not work, the COM port works with archi lab, but not I can get it to work with icestudio and verilog from other sites ;

Is the "Alchitry Cu and Io Pulldown Resistors" problem (see forums or review for old version of this board) fixed? My attempt at understanding the rev-2 2021-10-26 schematic would suggest things are still wired to VCC
