Netduino 3 for fast prototyping, in distribution

August 06, 2015 // By Graham Prophet
Distributor Mouser Electronics has the Netduino 3 platform, aimed at both quick-to-market commercial hardware solutions, and personal electronics projects, with maximum design flexibility and reduced risk. This newest version of the open-source Netduino platform includes, say its makers, the best of the features that made previous versions popular, with added Wi-Fi connectivity.

Netduino 3 is an open-source electronics platform designed around the Microsoft .NET Micro Framework, combining the ease of high-level coding and the raw feature set of the STM32 F4 family of microcontrollers. The 32-bit ST microcontroller on the Netduino 3 has a 168 MHz ARM Cortex-M4 processor with 2 MBytes of dual-bank, read-while-write flash memory and up to 256 kBytes of SRAM, including 64 kBytes of core-coupled memory (CCM). The Netduino 3 WiFi board supports 802.11b/g/n (2.4 GHz) Wi-Fi across open networks as well as through WEP and WPA2 protocols, and includes support for SSL 3.0 security, including TLS 1.2. The Netduino 3 Ethernet board features a 10/100 Mbps Ethernet port.

Like Netduino 2, this version features Arduino-compatible headers, including 22 GPIO pins with SPI, I²C, four UARTs (one RTS/CTS), and six PWM channels as well as six 12-bit analogue-to-digital converter (ADC) channels. The board also boasts three GoBus 2.0 ports for additional plug-and-play capabilities and a microSD slot for up to 2 GBytes of storage. Netduino 3 also includes upgradable firmware for increased functionality in the future.
