Realtek RTL8710AF (PADI IoT Stamp) vs Espressif ESP8266 (ESP-07) WiFi RF Performance Comparison

After I posted about PADI IoT Stamp IoT kit based on RTL8710AF ARM Cortex M3 WiSoC yesterday, I was soon asked whether I could compare the RF performance against ESP8266 modules like ESP-12. I don’t have any equipment to do this kind of test, except for some simple test like testing range with WiFi Analyzer app, but I remember Pine64 told me they had some comparison data a little while, and accepted to share their results. The test setup is comprised of Litepint IQ2010 multi-communication connectivity test system and PC software, as well as the device under test (DUT) with PADI IoT Stamp (version with u.FL antenna connector) and ESP-07 ESP8266 module as a u.FL connector is required to connect the test system. They’ve tested 802.11b, 802.11g, and 802.11n, but for IoT projects 802.11b is the most important as usually long range is more important than data rate. Test results […]

Pine64 PADI IoT Stamp WiFi IoT Kit Review – Part 1: Hardware, Debuggers, and Soldering

Back in September, Pine64 unveiled their $2 PADI IoT Stamp based on Realtek RTL8710 ARM Cortex M3 WiFi SoC aiming to compete with Expressif ESP8266 solutions. The company has now sent me their complete kit for review, which beside the module itself includes a breakout board kit, and some hardware debug tools. In the first part of the review, I’ll check out the hardware, and solder the kit. I received a package with four antistatic bags. From top left to bottom right, we have PADI IoT Stamp, JLINK-OB debugger based on an STM32 MCU with some jumper wires (aka Dupont cables) for SWD signals, and a USB cable to your computer in order to flash the firmware or do some bare metal programming, a breakout board kit including two headers, a RED LED, and a resistor, and finally a USB to Serial board based on CH340G with 4 jumper wires […]

Zidoo X8 Android TV Box, OpenWrt NAS, and HDMI Recorder Sells for $109

I posted my review of Zidoo X9S Android TV box, HDMI recorder and OpenWrt NAS a few days ago, and despite some limitations with regards to 4K video playback, the device is working pretty well. The $140 price tag might be a little more than some people are ready to pay, and the good news is that the company has now launched a cheaper model based on the same processor called Zidoo X8, without the external SATA port, and less storage. Zidoo X8 specifications: SoC – Realtek RTD1295 quad core Cortex A53 processor @ 1.4 GHz with ARM Mali-T820 MP3 GPU System Memory – 2 GB DDR3 Storage – 8 GB eMMC flash + micro SD slot + SATA 3.0 interface Video I/O – HDMI 2.0a output, AV output and HDMI 2.0 input (Support up to 4K60 input, but record/stream up to 1080p @ 30 Hz) Audio I/O – HDMI […]

Zidoo X9S Android Media Center Review – Part 2: Android Firmware & OpenWrt (NAS Functions)

Zidoo X9S is more than a simple Android TV box, as it supports NAS function via OpenWrt running simultaneously with Android 6.0 and its USB 3.0 and SATA ports, as well as HDMI input function capable of recording and broadcasting videos, and supporting Picture-in-picture, so I find “Android Media Center” better fit the description for this device. I’ve already taken pictures of the Zidoo X9S and its board in the first part of the review, so I’ll test both Android 6.0 & OpenWrt firmware, and the most of the features in the second part of the review. Initial Setup and First Boot I connected the usual accessories and cables to the box including a USB 3.0 hard drive, HDMI and Ethernet cables, USB RF dongles for MINIX NEO A2 Lite air mouse and Tronsmart Mars G01 gamepad, and a USB keyboard to take screenshots. I also added a 1TB SATA […]

Zidoo X9S Android TV Box HDMI Input Testing – Video Recording, PiP, and UDP Broadcasting

One of Zidoo X9S media center‘s key features is its HDMI Input port with support for PVR, picture-in-picture, and video broadcasting over UDP. The company has come a long way since the implementation of HDMI input on Zidoo X9 TV box, which would only support PVR function, and exclusively work in the foreground. For this review, I connected K1 Plus T2 S2 Android TV box to the HDMI input of Zidoo X9S, and started HDMI In app.The first good news is that HDMI input does work, as we can see K1 Plus user interface preview inside Zidoo X9S’ HDMI IN app. Before testing all features, let’s go through the options for Video, Audio, and Output. You can select various video resolution up to 1080p, but I left it to Auto, which for this test meant 1080p. Framerate cannot be changed and is set to Auto, while bitrate ranges from 1M […]

4K Video Playback and HDMI Audio Passthrough in Realtek RTD1295 based Zidoo X9S TV Box

Zidoo X9S is a high-end 4K TV box and HDMI recorder based on Realtek RTD1295 processor. I’ve already checked its hardware, and run some benchmarks, so after a successful OTA firmware update, I decided to test 4K videos and HDMI audio pass-through capabilities of the device with ZDMC, Zidoo’s fork of Kodi 16.1, and “Media Center” internal player. Before starting playing 4K videos and testing HDMI audio pass-through, you’ll want to make sure to configure video output to a 4K UHD resolution and framerate such as 3840×2160 @ 60 Hz, as well as change HDMI output audio in Sound & notification settings. The options are a little different from the other boxes as beside RAW and 2-channel LPCM, Zidoo X9S also supports multi-channel LPCM. In order to test HDMI audio pass-through, it must be set to RAW. You may also want to check Playback options to switch to 24 Hz […]

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 […]

Zidoo X9S Realtek RTD1295 Android & OpenWrt TV Box System Info & Benchmarks

Zidoo X9S is the first Android TV box based on Realtek RTD1295 quad core Cortex A53 processor that I’ve received for review. So in this post, I’ll show some system information with CPU-Z, and Android & OpenWrt Settings, and run typical Android benchmarks such as Antutu 6.x, Vellamo, and 3Dmark. Zidoo X9S / Realtek RTD1295 Android System Info CPU-Z detects Realtek RTD1295 is a quad core ARM Cortex A53 processor clocked between 600 MHz and 1.4 GHz with an ARM Mali-T820 GPU, and uses an unknown governor… But in adb shell, tje command “cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor” reports an ondemand governor is used. The system runs Android 6.0.1 on top of Linux 4.1.17 (I think it’s the first time I see a Linux 4.x kernel used in a TV box…), and with 1920×1080 resolution. Total RAM is shown to be 1672 MB, most probably because some RAM is reserved for the GPU […]
