Radiona ULX3S Open Source Hardware ECP5 FPGA Development Board Launched for $99 and Up (Crowdfunding)

ULX3S Lattice ECP5 FPGA Educational Board

Last summer, we wrote about Radiona ULX3S education board combining a Lattice Semi ECP5 FPGA with an Espressif Systems ESP32 WiFi & Bluetooth WiSoC. Designed for a digital logic course at the University of Zagreb, the board is open-source hardware with KiCAD hardware design files released on GitHub, and programmable with the Arduino IDE (FPGArduino) and ProjectTrellis open-source toolchain. At the time, there was only a version based on Lattice ECP5 85F with 84K LUT, but they’ve now made versions with cheaper variants of ECP5 FPGA and launched the board on Crowd Supply. Radiona ULX3S specifications: FPGA (one of the other) Lattice ECP5 LFE5U-85F-6BG381C with 84K LUT Lattice ECP5 LFE5U-45F-6BG381C with 44K LUT Lattice ECP5 LFE5U-12F-6BG381C with 12K LUT System Memory – 32MB SDRAM @ 166 MHz Storage – 4–16MB Quad-SPI Flash for FPGA config and user data storage; MicroSD slot Audio – 3.5 mm jack with 4 contacts (analog […]

Meshtastic Mesh Networking Project Combines ESP32, LoRa and GPS Radio

Meshtastic is a project using off-the-shelf, inexpensive ESP32-based hardware with GPS & LoRa connectivity to create mesh networks helping hikers. skiers, paragliders, or people exercising other outdoor activities communicate short messages such as their GPS location. This allows each member of a private mesh network to see the location and distance of all other members and read/or any text messages sent to a group chat. No phone is required unless you have an ESP32 LoRa board without GPS in which case it would get the GPS coordinates from your phone over Bluetooth. A phone is also needed to send a message. The project currently works on three different boards TTGO T-Beam, TTGO LORA32 and Heltec LoRa 32. The T-Beam is recommended as it sells for around $26 plus shipping and features a 18650 battery holder so you can source the battery easily locally. Just make sure to purchase the right […]
