For Python FPGA Development Board 1.0E Graphical Programming Easily Runs RISC-V Popis

LatTIce iCE40UP5k FPGA is used for core devices
The 5280 logic unit (4-LUT+CARRY+FF) has the same FPGA resources as our LatTIce version and less logic resources than the Altera version;
120 Kbit dual port RAM
1 Mbit (128 KByte) single port RAM, which exceeds the internal memory capacity of the FPGA used by us, is the reason it can support CNN;
PLL, 2 x SPI, 2 x I2C hardened IPs. Two internal oscillators (10 kHz and 48 MHz) greatly simplify the design. Eight DSP multiplier blocks are used for signal processing, such as voice synthesis and software defined radio;

Very low power consumption for battery powered applications
3 x 24 mA drives and 3 x hard IP PWM (can directly drive RGB LED lights and small current motors)
Enough, fast enough memory
128 Mbit (16 MB) quad SPI double data rate (QSPI-DDR) flash
For example, video stream can be transmitted to LED lattice
A lot of I/O (actually, there are few pins of UP5K FPGA, but they are enough)
3 pins for RGB LED
2 LEDs for board
One UART port, RX pin and TX pin can be accessed through virtual USB serial port
One key
Two Pmod connectors (total 16x pins)
There is a Pmod (8 x pins) that can be broken off
5 star shaped LED lights
3 keys
Sufficient resources to support the CPU soft core!

RISC-V and other soft cores
board FPGA programmer and USB to serial adapter
Compatible with IceStorm iceprog tool
Simple, no drive required to connect with the host
Pmod connector and Pmod module
This board has three kinds of standard Pmod connectors, which can be expanded very much - you can use many ready-made Pmod modules in the market, or you can design your own dedicated Pmod modules, for example, they developed seven segment digital tube Pmod, DIP Pmod, LED screen drive
