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 […]

Seeed IoT Button for AWS Brings Back Amazon Dash Button to Life for Developers

Amazon introduced $5 dash buttons in 2015 to let consumers purchase regular items such as washing powder by simply pressing a button. Some people hacked them for other purposes, for instance as WiFi logging buttons, but the company eventually stopped selling the buttons in February 2019 and fully killed those at the end of August. Seeed Studio is bringing back Amazon Dash button to life in some ways, with the Seeed IoT Button For AWS Wi-Fi-based, programmable button that deploys the AWS IoT 1-Click service. Seeed IoT Button for AWS hardware specifications: MCU – Dual-core MCU with 20MHz Cortex M0 and 200MHz Cortex M4F (Very likely Realtek RTL8720DN Wireless MCU) Storage – 4MB flash Connectivity – Dual-band Wi-Fi 4 802.11 a/b/g/n (2.4GHz & 5GHz) and Bluetooth 5.0 LE USB – 1x USB Type-C port for charging Misc – Button good for 100,000 cycles, 3x LEDs (red, green, blue) Power Supply […]

$11 DIGOO DG-R611 WiFi Repeater Comes with Two External Antennas

Low-cost WiFi routers such as A5 V11 mini router have been around for many years. The cheaper ones are usually powered by a USB charger sold separately, and support 2.4 GHz WiFI with a single antenna. But I’ve just noticed DIGOO DG-R611 WiFi repeater with support for dual-antenna, data rate up to 300 Mbps, and integrated power supply. It is sold for under $11 on Banggood and Aliexpress, and may be worth a closer look. DIGOO DG-R611 specifications: SoC – Realtek RTL8196E RISC processor @ 400 MHz System Memory – TBD Storage – TBD Networking Wired – 10/100M Ethernet port Wireless 2.4 GHz 802.11b/g/n WiFi 4 up to 300 Mbps Two 2dBi antennas Wireless Transmit Power – 20dBm(MAX EIRP) Repeater, Access Point (AP), or Media bridge modes supported Wireless Security – 64/128-bit WEP, WPA/WPA2, WPA-PSK/WPA2-PSK (TKIP/AES) Power Supply – Integrated 110-230V with US, EU, or UK plug Dimensions […]

Realtek RTL8720DN Dual-Band WiFi & Bluetooth 5.0 IoT Modules Sell for $4 and Up

BW16 RTL8720DN Dual-band WiFi & Bluetooth Module

There are plenty of 2.4 GHz WiFi modules for IoT project based on processors ranging from Espressif Systems ESP8266 to TI CC3200, or Realtek RTL8710. Some others add Bluetooth 4.2/5.0 such as Espressif Systems ESP32, but it’s much harder to find solutions with dual-band WiFi especially if you have a tight budget for your project or product. But Realtek RTL8720DN – part of AmebaD family – offers just that with the Arm Cortex-M4/M0 wireless MCU supporting dual-band (2.4/5.0GHz) 802.11 b/g/n WiFi and Bluetooth 5.0 connectivity, and found in modules currently selling for as low as $3.90 or 24 RMB in single units.

Ameba Z2 IoT Board Features Realtek RTL8720CM Armv8-M KM4 Secure Wireless MCU

In 2016 we discovered Realtek Ameba wireless microcontrollers combining an Arm Cortex-M3 core with WiFi connectivity, and that could potentially become an ESP8266 competitor with modules selling for as low as $2. But the solution never really took off, because it was about the same price as ESP8266, and the latter already had a solid software ecosystem and community. But RealTek has now introduced a new Ameba Z2 IoT development board powered by RTL8720CM microcontroller featuring an Armv8-M KM4 core clocked at 100 MHz. What’s an Arm KM4 core you may ask? Seeed Studio informed me Arm and RealTek worked together on the KM4 core, so it looks like a custom Armv8-M microcontroller. Ameba Z2 IoT Development Board Ameba Z2 (ZII) specifications: Wireless MCU – Realtek RTL8720CM single core Armv8-M KM4 core @ 100MHz with 4.2MB internal RAM, WiFi and Bluetooth radios Storage – 2MB external flash on module Connectivity […]
