Google Cloud IoT Core Enters Public Beta, Various Devkits Available

Back in May, I wrote about Allwinner R18 based Banana Pi BPI-M64 Board with Google Cloud IoT Core support, as Google unveils the new cloud service during Google I/O. However, at the time it was only available to selected partners, and Google has recently launched the public beta making their IoT device management platform available to all. I first learned about this through an ARM community blog post announcing availability of the ARM-based IoT Kit for Cloud IoT Core on Adafruit using Raspberry Pi 3 board,  a breadboard, and various modules that can be managed through Google services. But that are plenty of other IoT kits or boards for Google Cloud IoT Core including: Allwinner R18 based Pine A64-LTS, Banana Pi BPI-R18 Marvell based MACCHIATObin, and ESPRESSOBin boards Mongoose OS IoT starter kit with ESP32 board( instead of Raspberry Pi 3) Grove IoT Commercial Developer Kit based on Intel NUC DE3815TYKE Sierra Wireless mangOH Red Realtek Ameba-RTL8195AM Argon i.MX6UL Development …

Realtek RTL8195AM Ameba WiFi + NFC Module Sells for $9 Shipped

Last year, Realtek Ameba IoT SoCs and development kits launched with boards such as Ameba Arduino, and later, the family got some buzz thanks to $2 RTL8710AF modules like Pine64 Padi IoT stamp, which looked competitive priced against ESP8266 SoC, and featuring an ARM Cortex-M3 core. Back to 2017, ESP8266 appears to still be the preferred platform for makers, and the community around Reatek Ameba processor is relatively small, but maybe the solutions are being integrated into commercial products rather than hobbyists project. Today, as I browsed the web, I noticed that are also some Realtek RTL8195AM module with WiFi, and NFC starting with an “Realtek Ameba-RTL8195AM WiFi & NFC Module” I first found on DFrobot for $15 per unit, but after spending a bit more time searching, I ended finding what looks like the same model for $8.99 including shipping on IC Station. RTL8195AM module (MJIOT-AMB-02) specifications: SoC – Realtek RTL8195AM ARM Cortex-M3 processor @ 166 MHz with 1MB …

Realtek RTL8710BN ARM Cortex M4 WiFi MCU, MJIOT-AMB-03 Module & Board, and Ameba 4.0a SDK

We’ve already covered Realtek Ameba ARM Cortex M3 WiSoC several times with their RTL8710AF, RTL8711AM and RT8195AM solutions, but the company has now a new “Ameba Z series” relying on an ARM Cortex M4 core starting with RTL8711BN MCU. RTL8710BN specifications as listed on Realtek website: CPU – ARM Cortex-M4(F) up to 125MHz with FPU (TBC) Memory – 256KB embedded SRAM Storage – 512KB embedded ROM, external flash interface; XIP (eXecut In Place) support Wi-Fi 2.4GHz 1T1R 802.11b/g/n up to 150Mbps; 20MHz and 40MHz WEP, WPA, WPA2, WPS support Security engine – MD5, SHA-1, SHA2-256, DES, 3DES, AES Peripheral Interfaces SDIO Slave 2x UART SPI interface (Master/Slave) 2x I2C interface ADC for voltage management 5x PWM Up to 17x GPIOs Package – QFN-32; 5 x 5 mm AFAIK, other Ameba MCUs do not support XIP, but RTL8710BN and this lowers memory requirements since code can be executed from storage. MJIOT-AMB-03 module – pictured at the top of this post – is …

$8.80 RAK CREATOR Pro Ameba RTL8711AM WiFi IoT Board Comes with 2MB SDRAM, Up to 64MB SPI Flash

Realtek Ameba is a family of WiFi ARM Cortex M3 micro-controllers for IoT applications, and RTL8710AF got some buzz last year, as modules would sell as low as $2, hereby competing with ESP8266 in terms of price. While the solution was interesting, the community activity around the solution has been slow as ESP8266 already have the community and software support. Other Realtek RTL8195AM and RTL8711AM processors offer much more memory, but at the time, price was not as attractive with Ameba Arduino board based on RTL8195AM selling for $25. But there’s now a new Arduino compatible board made by ShenzhenRAK Wireless Technology (RAK) that comes with RTL8711AM processor with 1MB ROM, 2MB SDRAM, 512KB SRAM, and up to 64MB SPI flash, and sells for just $8.80 + shipping on Aliexpress. CREATOR Pro (Wiskey) board specifications: WiFi Module – RAK473 with Realtek RTL8711AM ARM Cortex M3 MCU @ 166 MHz, 1MB ROM, 2MB SDRAM, 512KB SRAM External Storage – Up to …

RTL8710 Ameba Arduino Development Board and Ameba Arduino v2.0.0 SDK Released

We’ve already seen a NodeMCU lookalike board called RTLDuino based on Realtek RTL8710AF ARM Cortex M3 WiSoC earlier this month, that can be programmed with a community supported Arduino port also called rtlduino via a JLink SWD debugger, but now Realtek has just launched Ameba RTL8710 Arduino board, and released Ameba Arduino v2.0.0 SDK which brings official Arduino support to RTL8710AF platforms. There appears to be two versions of the development kit: RTLDUINO_PRO_V1.0 and REALTEK-AMEBA_RTL8710_V2.0, but based on the user manual they seem to be identical, and as you can see from the above picture, it includes a baseboard and the aforementioned RTLDuino board. RTL8710 Ameba Arduino HDK key features: SoC – Realtek RTL8710AF ARM Cortex-M3 MCU @ 83 MHz with 802.11 b/g/n WiFi, hardware SSL engine connected to the baseboard via: RTLDuino board through female header B&T RTL-00 module soldered on module footprint USB – 2x micro USB ports, CON2 used for power and Arduino programming, CON1 used for …

Pine64 Unveils $2 PADI IoT Stamp WiFi IoT Module with FreeRTOS SDK, Upcoming ARM mbed 5.0 Support

Realtek RTL8710 WiFi IoT modules came out as potential competitors to ESP8266 modules last month, with similar features. an ARM Cortex M3, and a pricing as low as $2 in quantities. However, documentation is often in Chinese only, and based on my experience with an RTL8710AF module limited to AT commands set for now. Software and documentation are likely to improve a lot however, as Pine64, the makers of Pine A64 boards, are about to launch their own “PADI IoT Stamp” RTL8710AF module for just $1.99 in any quantities. PADI IoT Stamp specifications: SoC – Realtek RTL8710AF ARM Cortex-M3 @ 83 MHz with 1MB ROM, 512KB RAM, and 1MB flash Connectivity – 802.11 b/g/n WiFi @ 2.4 GHz – 2.5 GHz (2400 MHz – 2483.5 MHz) with PCB antenna; Station / SoftAP / SoftAP + Station modes; Expansion headers – 22 half-holes with Up to 1x SPI @ 41.5 Mbps max Up to 3x UART with 2x up to 4Mbps, …

Development Resources for Realtek “Ameba” RTL8710, RTL8711, and RTL8195 WiFi SoCs

We were made aware of a potential ARM based ESP8266 competitor last week with Realtek RTL8710 WiFi modules selling for about $3.5 shipped per unit, and under $2 per unit for larger orders (100+ pieces). Hardware is good, but for a platform to be successful, or even just useful, you also need software support. So I started doing some research into IoT-Tech BBS and asked ICStation for an “SDK” for the module they sold. I ended up on this forum post providing an “Realtek RTL8710 SDK” via Baidu (password: brwp), which turned out to be about the same as the Google Drive link provided by ICStation, and only contain minimal documents, as well as cracked Windows IAR Embedded Workshop and JLink tools. There are also some more technical details in Chinese only in another forum post, and well as B&T RTL8710 module datasheet (PDF). However, if you don’t read Chinese that’s pretty challenging, and you may not want to use …
