RAK Wireless Introduces LoRa + BLE Module, LoRa GPS Tracker, and NB-IoT/eMTC Arduino Shield

We’ve previously covered several products from RAK Wireless, including RAK WisCam Arduino compatible Linux camera, RAK CREATOR Pro Ameba RTL8711AM WiFi IoT board, and WisCore modular development kit for application leveraging voice assistants such as Amazon Alexa. AFAIK, the company had not released any new products since their RAK831 LoRa gateway module launched last summer, but they just contact me with the release of three new wireless products, namely RAK813 BLE + LoRa module, RAK811 LoRa tracker board, and WisLTE NB-IoT/eMTC/eGPRS Arduino shield. RAK813 BLE + LoRa module & Development Board Main features and specifications: Connectivity LoraWAN via Semtech SX127x (LoRa) chipset Frequency Ranges 433MHz, 470MHz FCC Frequency range 902~928MHz CE Frequency range 863~870MHz MIC Frequency range 920~928MHz KCC Frequency range 920~923MHz Receiver Sensitivity: LoRa down to -146 dBm TX Power – adjustable up to +14 dBm, max PA boost up to 20dbm Range – Up to 15 km in rural […]

RAK WisCam is a $20 Arduino Compatible WiFi Camera Linux Board Powered by Nuvoton N32905 ARM9 Processor

A couple of weeks ago I wrote about Rakwireless’ RAK CREATOR Pro development board based on Realtek Ameba RTL8711AM Wireless MCU, and part of their Wiskey family of development boards. Sub-family include WisNode for IoT boards, WisAP for OpenWrt boards, WisPLC for PLC hardware, and WisCam for WiFi video camera boards. The company has recently introduced Wiscam RAK5281 Arduino compatible Linux board powered by a Nuvoton ARM9 MCU, and supporting a camera module or an SD card + USB module. RAK WisCam specifications: SoC –  Nuvoton N32905R3DN ARM926EJ processor @ 200 MHz with 8KB internal SRAM, 16KB IBR internal booting ROM, 16Mbit  x16  DDR2 memory Storage – 128 MBit SPI flash, included sub-module adds micro SD card Connectivity – 802.11 b/g/n WiFi via Realtek RTL8189FTV module Camera via sub-module 648×488 pixel VGA CMOS Image Sensor (GC0308); 102° FOV Video –  QVGA (320×240) 30FPS, VGA(640×480) 30FPS, MJPEG encoding Photo – JPEG, […]

$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 […]
