ESP32-S2-Saola-1 Development Board is Now Available for $8

Espressif ESP32-S2 WiFi SoC mass production started at the end of February 2020, and soon enough we started to find ESP32-S2 SoC and modules for $1 to $2 on sites like Digikey, but so far we had not seen ESP32-S2 development boards for sale. The good news is the breadboard-friendly ESP32-S2-Saola-1 development board has started to show up for $8 on resellers such as Mouser and Digikey albeit with a lead time of 8 to 12 weeks. ESP32-S2-Saola-1 specifications: Supported modules – ESP32-S2-WROOM(-I) & ESP32-S2-WROVER(-I) with 4 MB SPI flash and for ESP32-S2-WROVER modules only, 2 MB PSRAM USB – 1x Micro USB port for power and programming / debugging via USB-to-UART bridge Expansion – 2x 20-pin I/O headers with SPI, I2S, UART, I2C, touch sensors, PWM, etc… Misc – Boot and reset buttons, RGB LED, 3.3V power on LED Power Supply (3 methods) 5V via Micro USB port (default) […]

PicoCore MX8MN is a Tiny NXP i.MX 8M Nano Computer-on-Module

The PicoCore MX8MN Nano carries the NXP i.MX 8M Nano F&S Elektronik Systeme has announced the development of the smallest i.MX 8M based CoM yet: the PicoCore MX8MN Nano. Previously we had reported on the Congatec Conga-SMX8 Nano which was a fairly small CoM compliant with SMARC 2.0 standard. The PicoCore MX8MN is based on the NXP i.MX 8M Nano CPU with 1 to 4 Arm Cortex-A53 cores and a Cortex-M7 real-time core. The Nano is set to carry up to 8GB RAM and 32 GB eMMC, with optional WiFI/BT and support for -40º C to 85º C temperature ranges. Similar to Predecessor The PicoCore MX8MN Nano is very similar in structure to the PicoCore MX8MM Mini CoM, but with a different i.MX 8M Mini processor featuring the same Arm Cortex-A53 cores, but the Cortex M4 real-time core is changed to a more powerful Cortex-M7 core in the MX8MN Nano.

XMOS launches Xcore.AI, a scalable AI processor for the Edge

XMOS, known for its high-performance voice interfaces, is joining the AIoT bandwagon with the announcement of the Xcore.ai, a flexible and economical processor delivering high-performance AI, DSP, control, and I/O’s in a single device. IoT and AI have been one of the most trending topics and fields in the last decade. Both areas have seen large innovations in between them. Deep neural networks have become better, IoT deployment cost has also been greatly reduced, and most importantly, they both have a significant impact on multiple industries. An interesting trend recently is the emergence of applications merging AI and IoT together to form so-called AIoT applications. IoT will be the digital nervous system, while AI will become the brain that makes all the critical decisions which will control the whole system. AIoT has led to the development and deployment of what we call AI processors or AI modules that can be […]

Variscite Introduces i.MX 8M Mini and Nano SoM’s, Symphony Carrier Board

NXP i.MX 8M Mini and i.MX 8M Nano are lower cost and lower power variants of NXP i.M 8M processors manufactured using a 14nm FinFET process, and cutting some features such as HDMI and embedded DisplayPort, or hardware video decoder. NXP i.MX 8M Mini has been announced for over two years, so we’ve already written about many boards and systems-on-module (SoM) including Boardcon EM-IMX8M-MINI SBC, TechNexion XORE LGA SoM, or Congatec conga-SMX8-Mini SMARC 2.0 module among others. NXP i.MX 8M Nano is more recent, and we only covered a few announcements so far namely iWave Systems iW-RainboW-G34M-SM SoM and Conga-SMX8-Nano SMARC 2.0 computer-on-module. There’s now at least a third company working on a “Nano” module with Variscite announcing VAR-SOM-MX8M-NANO SoM together with a “Mini” version called VAR-SOM-MX8M-MINI, and Symphony carrier board and development kits. VAR-SOM-MX8M-MINI & VAR-SOM-MX8M-NANO Modules Both modules are part of Variscite VAR-SOM Pin2Pin family, and share the […]
