Ameba RTL8722DM Cortex-M33/M23 IoT Development Board Now Available for $23.90

Earlier this year, we noticed some RealTek RTK8720DN dual-band WiFi and Bluetooth 5.0 IoT modules, and quickly mentioned Ameba RTL8722DM development board available for under $50. If you found the price of the board a bit expensive for what it had to offer, the good news is that Ameba RTL8722DM Cortex-M33/M23 IoT development board is now selling for $23.90 on Seeed Studio or Good Display. Ameba RTL8722DM specifications: MCU ARMv8M Real-M300 Cortex-M33 compatible MCU @ 200MHz ARMv8M Real-M200 Cortex-M23 compatible MCU @ 20MHz Memory – 4.5MB embedded SRAM in SoC Storage – 2MB external flash Connectivity Dual-band 802.11 a/b/g/n 1×1 WiFi 4 (20/40MHz) Bluetooth 5 SIG Mesh networking Supports both central and peripheral modes Display – 8-bit LCD up to 645×645 resolution @ 30FPS or 6-bit LCD up to 527×527 resolution @ 60 FPS Audio Codec – ADC, DAC, I2S Security – Hardware cryptographic engine, Arm Trust-Zone, Secure boot, Wi-Fi […]

Olimex ESP32-S2-Devkit-LiPo WiFi Board Consumes as Little as 2uA in Sleep Mode

When we covered ESP32 powered TTGO T-Watch-2000 smartwatch this week-end, people noted that with a 350 mAh battery, the watch would last about 3.65 days considering a 4mA drain with the screen always off, WiFI and Bluetooth off, and around 65mA when the screen is on good for about 5 hours of continuous use without Bluetooth nor WiFi. But it’s possible to make a much more-efficient ESP32-S2 Wifi board, as demonstrated by Olimex with their upcoming ESP32-32-Devkit-LiPo based on ESP32-S2-Saola-1 with circuitry to support LiPo batteries. They designed the board with an ultra-low-power power supply circuit which makes current consumption during sleep only 6uA, 4 of which are due to the battery measurement resistor divider, meaning the board should consume only 2uA in sleep mode or about 10 times less than other ESP32 Olimex boards. When reviewed Qoitech Otii power measurement & DAQ tool, we also noted power consumption could […]

NVIDIA Jetson Developer Kits Comparison – Nano vs TX2 vs Xavier NX vs AGX Xavier

NVIDIA launched the Jetson Xavier NX developer kit yesterday, and I included a short comparison table in the announcement between Jetson Nano, TX2, Xavier NX, and AGX Xavier developer kits. But I thought it might be worthwhile to have a more detailed comparison in a separate post, so here we are. As expected, usually the more you spend on a board, the better the performance and features. The exception is Jetson TX2 which’s the same price as the new Jetson Xavier NX devkit but delivers about a fifth of the FP16 AI performance. So as today, there’s little reason to buy a TX2 board for a new project unless you need some of the required features that are missing on Xavier NX.

Banana Pi BPI-M4 SBC Gets 2GB RAM, Sells for $43

First unveiled in February 2019, Banana Pi BPI-M4 is a single board computer based on Realtek RTD1395 quad-core Cortex-A53 4K media processor and following Raspberry Pi 3B+ form factor pretty closely. BPI-M4 officially launched in June 2019 for just $38 with 1GB DDR4 RAM, but despite the 2GB RAM option being listed in the specification, the 2GB version of the board was not available, at least on Aliexpress. The good news is that Banana Pi BPI-M4 with 2GB RAM has just started selling for $43 plus shipping on Aliexpress, or in Taobao if you based in China. Banana Pi BPI-M4 2GB specifications: SoC – Realtek RTD1395 quad-core Arm Cortex-A53 processor with Mali-470 MP4 GPU System Memory – 2GB DDR4 RAM Storage – 8GB eMMC flash, micro SD slot up to 256GB, M.2 NVMe SSD Video Output – HDMI 2.0b port up to 4K @ 60 Hz, HDR support Video Decode […]

Stinger96 (NB-IoT + eMTC) and Avenger96 96Boards STM32MP1 SBCs Giveaway

96Boards, Arrow Electronics, STMicro, and Shiratech have joined hands to organize a giveaway event with up to 500 Avenger96 or Stinger96 boards going to lucky winners. I’ve already covered STM32MP1 powered Avenger96 SBC compliant with 96boards CE Extended specification, but I’ve never heard about Stinger96 board, so before going into the giveaway rules, let’s have a closer look at this new 96Boards board designed by Israel based Shiratech. Stinger96 96Boards NB-IoT + eMTC SBC Specifications: SoC – STMicro STM32MP157 dual-core Arm Cortex-A7 processor @ up to 650 MHz (4158 CoreMark) with Arm Cortex-M4F MCU @ up to 200 MHz (673 CoreMark), 708KB internal SRAM System Memory – 256M x 32-bit DDR3 (1GB RAM) Storage – 8Gbit SLC NAND Flash, MicroSD card slot Connectivity Gigabit Ethernet header (via Microchip KSZ9031RNX) GPS, NB-IoT & eMTC (LTE Cat M1) IoT cellular connectivity with 2G fallback via Quectel BG96 module, SIM card slot, and […]

NVIDIA Introduces Jetson Xavier NX Developer Kit, and Cloud-Native Support

NVIDIA Jetson Xavier NX SoM was launched last month for $459. But while some third-party carrier boards were also announced at the time, the company had yet to offer Jetson Xavier NX Developer Kit as they did for Jetson Nano. But as GTC 2020 conference is now taking place in the kitchen of Jensen Huang, NVIDIA CEO, the company had plenty to announce including Jetson Xavier NX Developer Kit as well as “Cloud-Native” support for all Jetson boards and modules. NVIDIA Jetson Xavier NX Developer Kit Specifications: CPU – 6-core NVIDIA Carmel ARMv8.2 64-bit processor with 6 MB L2 + 4 MB L3 cache GPU – NVIDIA Volta architecture with 384 NVIDIA CUDA cores and 48 Tensor cores Accelerators 2x NVDLA Engines 7-Way VLIW Vision Processor Memory – 8 GB 128-bit LPDDR4x 51.2GB/s Storage – MicroSD slot, M.2 Key M socket for NVMe SSD Video Output – HDMI and DisplayPort […]

BeagleBone Green Gateway SBC with Ethernet, WiFi, and Bluetooth Launched for $60

BeagleBone Green Gateway SBC was first unveiled last July as an update to BeagleBone Green Wireless board with Ethernet, and Octavo Systems OSD3358 SiP along with some smaller changes like support for 12V power supply and I2C RTC + battery. The board did however lose two USB 2.0 ports to make space for the Ethernet connector. The board was not quite available at the time, but the good news is that you can now buy BeagleBone Green Gateway for $59.99 on Seeed Studio. Specifications have remained the same as the ones provided for the initial announcement: SiP – Octavo Systems OSD3358 with Texas Instruments AM3358 Arm Cortex-A8 processor @ 1.0 GHz, 2×32-bit 200-MHz programmable real-time units (PRUs), 3D graphics accelerator, 512MB DDR3 SDRAM, 4KB EEPROM, and integrated power management Storage – 4GB 8-bit eMMC on-board flash storage (Kington) + microSD socket Connectivity 10/100Mbps Ethernet (RJ45) WiFi 802.11 b/g/n 2.4GHz + […]

Teensy 4.1 Board Gets Longer for Ethernet, MicroSD Slot, and More GPIOs

What comes after Teensy 4.0? Teensy 4.1. The new version of the Arduino compatible board is powered by the same NXP i.MX RT1062 Cortex-M7 crossover processor clocked at 600 MHz, but about doubling in length in order to add a 10/100 Mbit Ethernet PHY, a MicroSD card slot, and offer more I/Os. Teensy 4.1 also increases flash memory to 8 MB (vs 2 MB for Teensy 4.0), and the USB hot-plugging power management circuitry needed to plug a USB device via a USB host cable. Teensy 4.1 specifications: SoC – NXP i.MX RT1062 Arm Cortex-M7 processor at 600 MHz with 1024KB RAM (512KB is tightly coupled), Storage – 8 MB serial flash (64KB reserved for recovery & EEPROM emulation), MicroSD Socket, footprints for 2x extra QSPI chips such as flash or 8MB PSRAM chip USB – 1x micro USB port for power and programming Networking – 6-pin Ethernet header via […]
