TTGO ESP32-S2 WiFi IoT Board Comes with Optional MicroSD Card and Battery Support

TTGO ESP32-S2 ESP32-S

All ESP32-S2 boards I’ve seen so far were from Espressif Systems themselves including ESP32-S2-Saola-1 and ESP32-S2-Kaluga-1, but LilyGO TTGO ESP32-S2 is the first third-party board for sale so far. The tiny board is somewhat similar to ESP32-S2-Saola-1 board and comes in two versions with a similar form factor, but a completely different pinout and the presence of a MicroSD card socket and a battery connector on one of the boards. The simpler board is called “ESP32-S2 ESP32-S-WOOR” and comes with ESP32-S2-WROOM module, while the one with more features is named “TTGO ESP32-S2 ESP32-S ” and features its own circuitry built around ESP32-S2 WiSoC. Both TTGO ESP32-S2 boards share many of the same specifications: SoC – Espressif Systems ESP32-S2 single-core 32-bit Tensilica LX7 processor with 320 kB SRAM, 128 kB ROM, System Memory – 8MB PSRAM Storage – 4MB flash; XY-ESP32-S only: MicroSD card socket Connectivity 2.4GHz 802.11b/g/n WiFi 4 connectivity Antenna XY-ESP32-S-WOOR: PCB antenna on module XY-ESP32-S: “3D” antenna USB …

Raspberry Pi 4 Gets 8GB RAM, Raspbian 64-bit (Beta)

Raspberry Pi 4 with 8GB RAM

The Raspberry Pi 4 Model B was launched in June 2019 with Broadcom BCM2711 Arm Cortex-A72 processor coupled with either 1, 2, or 4GB LPDDR4 RAM. But there were expectations that a Raspberry Pi 4 with 8GB RAM or an 8GB eMMC flash may be eventually launched, as some of the user guides read “Product name: Raspberry Pi 4 Model B 1 GB, 2 GB, 4 GB + 8 GB variants”. We now know the answer as the Raspberry Pi Foundation has just introduced Raspberry Pi 4 with 8GB RAM. Raspberry Pi 4 8GB specifications are the same except for the RAM capacity: SoC – Broadcom BCM2711 quad-core Cortex-A72 (ARMv8) @  1.5GHz with VideoCore VI GPU supporting OpenGL ES 3.0 graphics System Memory – 8GB LPDDR4 Storage – MicroSD card slot Video Output  & Display I/F 2x micro HDMI ports up to 4Kp60 3.5mm AV port with composite video (and stereo audio) 2-lane MIPI DSI display port Video Decode – …

Ryzen Embedded SBC is Made for Real-time AI Vision, Conveyor Belt Tracking

MIRU130 Ryzen Embedded-SBC Real-time AI Vision Conveyor Belts

Axiomtek just recently introduced CAPA13R AMD Ryzen Embedded V1605B/V1807B SBC in 3.5″ embedded SBC form factor, and the company is now back with another, larger Ryzen Embedded SBC: Axiomtek MIRU130. Why would they launch yet another Ryzne Embedded board two weeks later? Different applications. While CAPA13R targets various graphics-intensive applications ranging from medical imaging to smart digital signage, MIRU130 appears to be especially focused on real-time vision-based AI applications with PoE and USB ports for cameras, and integrated “real-time vision I/Os” such as trigger inputs, LED lighting controllers, camera trigger outputs and an encoder input designed for conveyor tracking. MIRU130 SBC specifications: SoC (One or the other) – AMD Ryzen Embedded V1807B or V1605B quad-core processor with Radeon Vega 8 graphics; V1807B: 35-54W TDP; V1605B: 12-25W TDP System Memory – 2x 240-pin DDR4-2400 SO-DIMM, up to 16GB RAM Storage 1x SATA-600 1x M.2 Key B (SATA, USB 2.0, PCIe x2 optional) in 22×42, 22×80 or 30×42 BIOS AMI Display – …

Dialog DA16200 WiFi SoC Promises a Year of Battery Life for Always-Connected IoT Devices

Dialog DA16200 WiFi One Year Battery Life

WiFi is omnipresent, and many IoT devices are relying on the wireless standard for connectivity, but as most of you will already know, WiFi suffers from high-power consumption and may not always be suitable for battery-operated devices. There are always battery optimization tricks to use WiFi on battery-powered devices, for example, a solar camera using PIR to only record and transmit video when needed,  or a board optimized to consume as little as possible in deep sleep waking up only when necessary. Those tricks are not applicable to all use cases, so Dialog Semiconductor has launched DA16200 Wi-Fi SoC delivering year plus battery life for always-connected Wi-Fi IoT devices. DA16200 key features and specifications: MCU Core – Arm Cortex M4F @ up to 160 MHz Memory – 512 KB SRAM Storage – 256 kB ROM, 8KB OTP ROM, external flash controller, eMMC, SD host Connectivity 2.4 GHz, 20 MHz channel bandwidth 802.11n 1×1 WiFi 4 up to 72 Mbps; WiFi …
