Olimex ESP32-EVB Board with Ethernet, CAN Bus, and Relays up for Sale for 26 Euros

One of the new feature of Espressif ESP32 SoC over ESP8266 is the inclusion of an Ethernet MAC interface, but so far few boards come with an RJ45 jacks. ESP32 Monster board is an option, also including an OLED Display and CAN Bus, and sold on Tindie for $35, but Olimex has now stocked their ESP32-EVB board with Ethernet, CAN Bus, and two relays, and you can purchase it for 26 Euros per unit, and less in larger quantities. Olimex ESP32-EVB Rev. B specifications: Wireless Module – ESP32-WROOM32 module with 802.11 b/g/n WiFi and Bluetooth LE Wired Connectivity – 10/100M Ethernet with RJ45 jack (via LAN8710A) External Storage – micro SD slot Relays – 2x 10A/250VAC relays with LED status Expansion 40-pin GPIO female header (2.54mm pitch) UEXT connector for sensors and modules CAN Bus USB – 1x micro USB port for debugging (CH340T) and power Misc – Reset and […]

22€ Olimex ESP32-EVB ESP32 Development Board Features an Ethernet Port and Relays

We already have a good choice of ESP32 development boards, but none of the ones I’ve seen make use of the Ethernet MAC interface found in Espressif ESP32 SoC. Olimex has changed that with their ESP32-EVB featuring ESP32-WROOM32 module as well as one Fast Ethernet port and two relays. Olimex ESP32-EVB specifications: Wireless Module – ESP32-WROOM32 module with 802.11 b/g/n WiFi and Bluetooth LE Wired Connectivity – 10/100M Ethernet RJ45 port External Storage – micro SD slot Relays – 2x 10A/250VAC relays Expansion 40-pin GPIO female header (2.54mm pitch) UEXT connector for sensors and modules Misc – 2x user buttons Power Supply 5V power jack LiPo charger and step up converter allowing ESP32-EVB to run from LiPo battery The company still have to write software samples, and do some testing to make sure the board work before going into mass production. Once everything is cleared, the board will be sold […]

ESP32-WROVER-KIT Devkit Supports Espressif ESP32 Modules, Includes a 3.2″ LCD Display

Yesterday Olimex wrote a blog post informing us that ESP32-CoreBoard was back in stock, one the many ESP32 boards launched late this year, but still hard to get. The company also mentioned they’d have limited quantity of the new ESP32-WROVER with JTAG and LCD display together with the picture below. ESP32 is quite more powerful than ESP8266 so it makes sense to have an ESP32 development kit with an LCD display. A quick DuckDuckGo search led me to ESP-WROVER-KIT Getting Started Guide, where we can find more details including the overall specifications: Compatible with ESP-WROOM-32 and ESP32-WROVER modules based on ESP32 dual core Tensilica L108 processor clocked at up to 240 MHz with WiFi and Bluetooth LE connectivity Storage – Micro SD slot Display – 3.2″ LCD display connected via SPI USB – 1x micro USB port Expansion 8-pin UART header 6-pin SPI header 48-pin header for I/Os and camera […]

Linux 4.9 Release – Main Changes, ARM and MIPS Architectures

Linus Torvalds released Linux 4.9 on Sunday: So Linux 4.9 is out, and the merge window for 4.10 is thus open. With the extra week for 4.9, the timing for the merge window is obviously a bit awkward, and it technically closes in two weeks on Christmas Day. But that is a pure technicality, because I will certainly stop pulling on the 23rd at the latest, and if I get roped into Xmas food prep, even that date might be questionable. I could extend the merge window rather than cut it short, but I’m not going to. I suspect we all want a nice calm winter break, so if your stuff isn’t ready to be merged early, the solution is to just not merge it yet at all, and wait for 4.11. Just so you all know (I already bcc’d the main merge window suspects in a separate mailing last […]

ESP32 Updates – ESP32-S Module Replaces ESP3212, ESP32 DevBoards for Sale, Arduino & NodeMCU Support

There have been some developments with regards to Espressif ESP32 in the last month since my post about upcoming ESP32 development boards. First ESP3212 module is no more, and has been replaced with ESP32-S module with about the same features, but it’s not pin-to-pin compatible, so the new module won’t work with older breakout boards made for ESP3212. ESP32-S is now out of stock on Seeed Studio, but you’ll find it on IC Station, Banggood, and others shops. One good news is that it’s now easier to buy – or at least pre-order – ESP32 development boards, although stock may still be an issue, as the platform is very popular. If you live in the US, you can now backorder “Sparkfun ESP32 Thing” for $19.95. ESP32 board can be powered by either a micro USB power supply or a LiPo battery, and exposes close to 30 I/O pins. ESP32 developer […]

Olimex A20-OLinuXino-LIME2-eMMC Board Replaces NAND by eMMC Flash for Better Performance & Reliability

A20-OLinuXino-LIME boards are the most popular development board sold by Olimex, likely thanks to reasonable pricing, and Allwinner A20 is one of the rare low cost processor to features an actual SATA interface and Gigabit Ethernet support. The company has now launched a new version A20-OLinuXino-LIME2-eMMC, based on A20-OLinuXino-LIME2-4GB, but replacing the NAND flash by an eMMC flash that should offer both better performance and reliability.

Olimex H3-OLinuXino-NANO is a Smaller Allwinner H3 Board with HDMI, Ethernet, and Many I/Os

Allwinner H3 processor is quite popular in development boards thanks to some of Shenzhen Xunlong’s Orange Pi boards such as Orange Pi PC or Orange Pi One. However, some specific features may not work 0ut of the box, or are undocumented, so it’s always a plus when more companies create boards for a platform, and that’s exactly what Olimex has done with H3-OlinuXino-NANO, a board that’s smaller than any Orange Pi boards, the first open source hardware Allwinner H3 board on the market, and featuring many more I/O pins available. Olimex H3-OlinuXino-NANO specifications: SoC – Allwinner H3 quad core Cortex-A7 processor @ 1.2 GHz with Mali-400MP2 GPU System Memory – 512MB of DDR3 RAM Storage – micro SD card slot Video Output- HDMI up to 1080p60 Connectivity – 10/100M Ethernet USB – 2x USB host ports + 1x micro USB OTG port Expansion – Optional 2x 40-pin headers with GPIOs, […]
