ESP8266 LED Matrix Clock

Simple LED matrix Clock based on the popular ESP8266 with Real Time Clock module and time synchronization over WiFi from an NTP server.

One note on the RTC module, apparently it also has the ability to charge the battery, however that’s not a good idea when using a CR2032. One possible solution would be to cut the trace marked on the image in order to disable the charging part of the circuit.

ESP32- Now With Long Range Wi-Fi

Nowadays, Wi-Fi is a word we hear often, and it is a technology that we use all the time. There are around 279 million Wi-Fi hotspots in the world, and in 2021 that number is expected to increase to 542 million hotspots. The wireless nature of this technology allows users to access a network from any convenient location. Wi-Fi chipsets are pieces of hardware designed for wireless communication and they are cheap, and readily available, but the range don’t match the expectations, and configuring its coverage is no easy task.

Support for the 802.11 LR mode in the ESP-IDF was added at the end of 2016. The 802.11 LR mode can achieve a 1 km line of sight range if both the station and the Soft-AP are connected to an ESP32 device.

ESP32 is a low cost, low power system on a chip (SoC) with Wi-Fi and Bluetooth capabilities. It was created for mobile devices, wearables electronics, and for Internet of Things applications. The devices have low power consumption. The EPS32 uses Tensilica Xtensa LX6 microprocessor and it was created by Espressif systems.

The mode was included quietly, so there has not been much talk about it, but some people noticed the inclusion, and have been testing the long-range mode in the field. Enabling the mode requires only a function call, making it easy to use. The long-range mode comes with a cost which is the data rate which is significantly reduced. In addition, a lot more can be done if the common router antenna is replaced by directional antenna.

This device has already been tested by some users for drones and long-distance applications, but there is no formal data about the device’s performance, problems, and even the applications are not clear enough. The recent increase in popularity could lead to conclusive data which could make the mode more reliable.

The applications for this includes remote drone video, telemetry (collecting data at remote or inaccessible points and transmitting it for monitoring), wardriving (finding Wi-Fi hotspots from a moving vehicle) etc. There are many possibilities, but we must give makers time to figure this new mode on their own, and to test its capabilities.

Banana Pi BPI-W2 SBC – A Multimedia Router And NAS Board That Runs Android Or Linux

SinoVoip has released Banana Pi BPI-W2 multimedia network and smart NAS router SBC. The BPI-W2 has a faster processor and more advanced features than last year’s Banana Pi BPI-R2. However, the new model has only two Gigabit Ethernet ports instead of four.

This SBC is designed for applications such as high wireless performance, home entertainment, home automation, and many more. The BPI-W2 runs on a Realtek RTD1296 SoC with 4x Cortex-A53 cores clocked at up to 1.5GHz with a high-end Mali-T820 MP3 GPU. By comparison, previous year’s BPI-R2 used a quad-core, Cortex-A7 MediaTek MT7623 with a Mali-450 MP4. SinoVoip confirms full support for Android 6.0CentOSDebian 9Raspbian, and Ubuntu 15.04, and the board is also said to support OpenWrt.

The updated I/O support is shown in the BPI-W2’s dual SATA III ports, compared to only one on the single SATA interface found on the MT7623-based BPI-R2 and RTD1295-based devices. The BPI-W2 also has 8-64GB eMMC, a microSD slot, and 2GB of DDR4.

Although limited to dual GbE ports, the board also has a GbE WAN port for router applications. Unlike the R2, there is an HDMI input in addition to the HDMI output, and a mini-DisplayPort has replaced the earlier MIPI-DSI connection. In either case, the output resolution is still limited to HD (1080p) only.

Four USB ports are available, including single USB 3.0 and Type-C ports. There is a 40-pin header that is claimed to support Raspberry Pi 3 add-on boards. Other features involve RTC, IR, debug, audio I/O, and a 12V input.

Like other Banana Pi boards, the BPI-W2 is open source, shipping with schematics and other documentation. The AliExpress and wiki pages list and show PCIe 2.0 and 1.1/SDIO slots on the front as well as a single M.2 slot on the back. Yet the PCIe slots are also tagged as M.2 slots (E-Key), and it’s unclear which slots are capable of what. The PCIe slots are capable to support up to 802.11ac WiFi, and there’s also a SIM card slot.

The Banana Pi BPI-W2 is available now for $93 plus shipping on AliExpress. More information may be found on the BPI-W2 wiki page.
