ESP32-C3-DevKit-Lipo RISC-V development board with build in USB JTAG, WiFi, Bluetooth5, Lipo charger and 15 GPIOs

ESP32-C3-DevKit-Lipo is EUR 6.00 Open Source Hardware compact development board with:

• RISC-V running on 160Mhz
• 400KB RAM, 8K data RAM
• 4MB Flash
• Two headers (soldered) with power supply and GPIO signals
• ESP-PROG-C compatible rescue connector (if you mess with bootloader)
• USB-C for programming and JTAG debugging
• LiPo battery charger allowing handheld applications with single LiPo battery
• 4 mount holes

This is all you need to get started with RISC-V programming in C and Assembly.

Shteryana Shopova recently did RISC-V workshop with this board and explained how to setup your tools for programming and debugging. Here you can find her work.

Hello RISC-V! We got samples of the new ESP32-C3 module and it is only 13×17 mm

We got some engineering samples of ESP32-C3 modules.

They are smaller than ESP32-WROOM and WROVER and measure just 17x13x2.5 mm!

This is the first Espressif product with RISC-V core, the datasheet is on their web.

This is also the first SOC with RISC-V core we have access to, so we are excited to learn more the ISA on low level.

Any resources to recommend? Is there something like small disassembler/monitor with few commands like read/write to memory and list code, which to allow you to write in assembly and run code?

Found this on GitHub today https://github.com/andportnoy/riscv-disassembler

TUXCON FOSS and OSHW conference 2018 in Plovdiv is just 18 days away, so plan your visit properly ;)

TuxCon 2018 conference about Free Open Source Software and Open Source Hardware will be June 9 and 10th in Plovdiv.

This is community driven event done by volunteers with the support of local IT companies and it’s totally free to participate.

In Saturday 9th of June in the Technical University building there will be two rooms, for lectures and workshops.

Hacking Risc-V core, implemented on iCE40 FPGA and playing with it’s instruction set and making small “monitor” program which allow you to enter programs written on machine code and executed on iCE40HX8K-EVB + iCE40-IO will be demonstrated, so if you want to touch and make your first program on RISC-V “computer” with VGA monitor and keyboard you may find Rangel Ivanov lecture interesting.

Plamen Vaisolov is retro computer maniac and keep working on them, implementing modern floppy disk emulators and other peripherials. He will share his experience with all these who miss Karateka and Load Runner 🙂

Neven Boyanov will talk about his experience with LoRA network and how to start on low budged.

Dimitar Gamishev has two interesting talks, one is for the Open Source Hardware and Software GPS car navigation he made. In the  second he will speak about the home assistants like Google Home and Alexa, how to implement them with small Linux computer like OLinuXino and even with ESP32-Lyra and how to impress your girlfriend by switching on and off appliances and lights with your voice.

There will be KiCAD workshop where everyone (even with no knowledge) will learn how to install, configure and make small robot PCB with KiCAD. Then some general knowledges about PCB materials and how to prepare all files and send to PCB board house for manufacturing. How to select the components, footprints, good routing practices, DRC/ERC checks, Gerber generation and tips how to design your PCBs in way to be produced at lower cost. At the workshop will be our design engineers and you can talk to them directly about issues you encountered when worked with KiCAD or other CAD product.

 

In Sunday 10th of June we will have traditional Soldering workshop at Olimex training building, where we will assembly and program with Arduino small robot which can follow line or escape from labyrinth. This will be the same robot which PCB we will design in the KiCAD workshop in the previous day. We will go detailed through the program and study how modifications affect it.

The workshop with end with barbeque in Olimex backyard 🙂

 

We are looking forward to see you in Plovdiv soon!

iCE40HX8K-EVB OSHW FPGA board is in stock

iCE40HX8K-EVB is upgrade of our iCE40HX1K-EVB with more logic cells FPGA so bigger Verilog projects could be synthesized.

GPIO1 34 pin bus is same as iCE40HX1K-EVB and all DAC, ADC, IO, etc modules are compatible, on top of this there are plenty of additional GPIOs on 4 40 pin 0.05″ step connectors.

512KB fast SRAM is on board, with iCE40-IO board you  can connect VGA monitor and PS2 keyboard, so you can make your own custom CPU (for instance RISC-V) computer with monitor and keyboard.
