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. B&T BW16 RTL8720DN Module Specifications: Wireless SoC – Realtek RTK8720DN MCU with KM4 Arm Cortex-M4 core @ 200 MHz and KM0 Arm Cortex-M0 core @ 20 MHz Connectivity WiFi 802.11 a/b/g/n WiFi 4 Frequency Range – 2.412-2.484GHz & 5.180-5.825GHz Data Rates 802.11a: 6,9,12,18,24,36,48,54Mbps 802.11b: 1,2,5.5,11Mbps 802.11g: 6,9,12,18,24,36,48,54Mbps 802.11n: MCS0–MCS7 @ HT20/HT40 2.4GHz and 5GHz bands AP, Station, AP/Client …

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

Ameba Z2 IoT Development Board

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 Wi-Fi – 802.11 b/g/n 1×1 Wi-Fi 4 (20/40MHz) with PCB …

Banana Pi BPI-M4 RPi 3+ Lookalike Board with 4K Video, M.2 Socket Launched for $38

Banana Pi BPI-M4

Banana Pi BPI-M4 was unveiled at the beginning of the year as an alternative to Raspberry Pi 3B+ with the same form factor, but equipped with a more capable processor, namely Realtek RTD1395 with support for 4K video output and decoding, Gigabit Ethernet support, PCIe, etc.. SinoVoIP has however made the choice not to go with Gigabit Ethernet, and opted for a cheaper design with Fast Ethernet instead. Having said that, the 4K capabilities of the processor, and PCIe via an M.2 socket are still leveraged in the company’s latest Banana Pi board. What’s changed is that Banana Pi BPI-M4 is now available on Aliexpress for $38 plus shipping in 1GB RAM + 8GB flash storage configuration. Banana Pi BPI-M4 specifications have not changed: SoC – Realtek RTD1395 quad-core Arm Cortex-A53 processor with Mali-470 MP4 GPU System Memory – 1 GB DDR4 (option 2 GB) Storage – 8G eMMC flash (max 64 GB), micro SD slot up to 256GB Video …

Banana Pi BPI-M4 Board Comes with RTD1395 Processor, M.2 Socket, Raspberry Pi 3B+ Form Factor

Banana Pi BPI-M4

Realtek RTD1395 processor is a lower cost version of RTD1295 / RTD1296 processors found in mid-range TV boxes often including HDMI input and output such as Zidoo X9s or LAKE I Home Cloud. The new processor comes with a lower-end Mali-470MP4 GPU and removed some interfaces like HDMI input and native SATA. So far, we had seen very few hardware platforms built around the processor, but SinoVoIP has just unveiled their latest Banana Pi BPI-M4 board powered by Realtek RTD1395 processor, following Raspberry Pi 3B+ form factor, and adding an M.2 key E socket with PCIe 2.0 and USB 2.0 signals.

RTD1395 TV Box

A few days ago, the U-boot & Linux source code for Realtek RTD1296 processor was released, and when we checked out the code we found out references to a completely new Realtek RTD1619 hexa-core Arm Cortex-A55 processor, as well as code for the previously announced Realtek RTD1395 processor. The CES 2018 announcement was really short on details though: “Realtek’s Android & RDK STB platform (RTD1395) supports 4K UHD, HDR, an advanced DRM security system, and OTT integration, giving MSOs a reliable SoC partner”.  We now have more details thanks to Taiwan based Compal Broadband Networks and their VIP1111 4K IP set-top box powered by RTD1395 processor.VIP1111 TV box specifications: SoC – Realtek RTD1395 quad core Cortex-A53 processor, Arm Mali-470 MP4 GPU System Memory – 2GB DDR4 (4x 512MB x 16bit) Storage – 8GB  eMMC Flash Video & Audio Output – HDMI 2.0 Video Codec – HEVC 4Kp60+2Kp60, VP9.2 4Kp60, HDR10 Connectivity 802.11 ac/abgn Dual Band 2.4G/5G 2×2, Wave-2 compatible with …
