Giveaway Week 2025 winners announced!

CNX Software’s Giveaway Week 2025 has just ended and we’ve now ready to announce the winners. We offered some of the review samples we tested, and three companies joined us offering new samples, namely Banana Pi with two router boards, VOIPAC with an industrial development kit, and RAKwireless offered two of their IoT development kits for the fifth year running. Besides the aforementioned prize, we also included an ESP32-P4 development kit, a dry switch from SONOFF, a Raspberry Pi CM4-based HMI with a 915MHz LoRa module, a 5-inch Raspberry Pi Touch Display, and two USB PD voltage indicators on both CNX Software “International” and CNX Software Thailand. You can see all prizes shown below. Without further ado, here are the seven winners of Giveaway Week 2025 on CNX Software (English): M5Stack M5Tab – Ed, Canada Elecrow Pi Terminal – Tom, Finland Banana Pi BPI-R4 Lite router board – Stef, Belgium […]

Giveaway Week 2025 – RAKwireless Blues.ONE LoRaWAN, LTE-M, and NB-IoT devkit

It turns out we don’t have two, but three companies offering free samples on CNX Software this year. The last one is a regular, and RAKwireless joins us for the fifth year running with a Blues.ONE LoRaWAN, LTE-M, and NB-IoT devkit that can be useful for industrial automation and asset-tracking applications. Regular readers may recall that it is the same prize as last year. While I usually prefer getting a new devkit, the company didn’t launch any this year (just some Meshtastic kits). The good news is that if you missed out last time around, you have a chance to give it another go. Here’s what the winner will get as a reminder: RAK4631 WisBlock Core Module based on Nordic Semi nRF52840 Arm Cortex-M4F microcontroller @ 64 MHz with 1 MB Flash, 256 KB RAM, Bluetooth Low Energy 5.0 protocol stack Semtech SX1262 LoRa Transceiver with LoRaWAN 1.0.2 protocol stack […]

Giveaway Week 2025 – VOIPAC iMX93 Pro industrial development kit

The sixth prize of this year’s Giveaway Week is a VOIPAC iMX93 Pro industrial development kit with an NXP i.MX 93 Cortex-A55/M33 Edge AI SoC, 2GB LPDDR4, and 16GB eMMC flash. The development kit offers dual Gigabit Ethernet, WiFi 6, and Bluetooth 5.3 connectivity, HDMI, DisplayPort, and HDMI display interfaces, three audio jacks, two MIPI CSI camera interfaces, various USB ports, M.2 sockets, and more. It targets artificial intelligence, machine learning, human-machine interface (HMI) solutions, and more. I reviewed the VOIPAC IMX8M industrial development kit and subsequently gave it away in 2023, but I haven’t done a review of the iMX93 development kit. Instead, one lucky winner will get it directly from VOIPAC. Alternatively, they can offer the new iMX91 industrial development kit, if you prefer. You can also write your preferred kit in the comments (optional). The company provides Linux built with Yocto Project 5.0 Scarthgap for the […]

Giveaway Week 2025 – USB Vsense USB PD voltage indicator

The fifth prize of CNX Software Giveaway Week 2025 will be the USB Vsense USB PD voltage indicator. I received three samples for review last August, so I’m keeping one for myself, giving one here on CNX Software (International), and another one on CNX Software Thailand. It’s a simple device with two USB-C ports and color-coded LEDs showing the voltage supported from 5V up to 48V as defined in the Extended Power Range (EPR) specs. In my review, I found the little device to work as expected, testing it with various USB PD adapters connected to a laptop and a Raspberry Pi 5 SBC. There are already such USD PD voltage testers on the market, and what differentiates the Vsense from the rest is its multi-layered design, since it’s made of seven PCBs stacked on top of each other and secured with four screws. To enter the draw, simply leave […]

Giveaway Week 2025 – 5-inch Raspberry Pi Touch Display 2

The fourth prize of CNX Software Giveaway Week 2025 will be the official 5-inch Raspberry Pi Touch Display 2. I was sent one for review, but I have yet to find anything interesting to use it for, like I did for the 7-inch Raspberry Pi Touch Display 2 and the Raspberry Pi AI camera. So I might just as well give it away. To enter the draw, simply leave a comment with your country and whatever else you’d like to say (no links in the body of the comment). If the country is missing, I’ll consider the entry void. Other rules are as follows: Only one entry per contest. I will filter out entries with the same IP and/or email address. Contests are open for 48 hours starting at 10 am (Bangkok time) every day. Comments will be closed after 48 hours. If comments are open, the contest is still […]

Giveaway Week 2025 – Banana Pi BPI-R4 Lite

Mediatek Filogic 850 2.5GbE WiFi 7 5G router board

The third prize of CNX Software Giveaway Week 2025 is the Banana Pi BPI-R4 Lite router board, which will be shipped directly to a randomly selected winner by the company. It’s powered by a MediaTek Filogic 850 (MT7987AV) quad-core Cortex-A53 network processor, coupled with 2GB DDR4 and 8GB eMMC flash, and equipped with four gigabit Ethernet ports, a 2.5GbE RJ45 WAN port, and a 2.5GbE SFP cage. It can also be extended with WiFi 7 and 5G cellular modules thanks to two mini PCIe sockets and an M.2 Key-B slot with USB 3.0 interface. The board also features a 16-pin MikroBus GPIO header with UART, I2C, SPI, PWM, and other signals to connect one of the over 1000 Mikroe Click modules available. As its name implies, the BPI-R4 Lite is a cost-down version of the Banana Pi BPI-R4 introduced a few years ago. The documentation has improved since the last […]

Giveaway Week 2025 – Elecrow Pi Terminal Raspberry CM4 industrial HMI display

Elecrow CrowPanel CM4 Pi Terminal Demo application

Sometimes we receive samples even though we did not ask for them, said we would have time to review them, or due to miscommunication. That’s exactly what has happened with the Elecrow Pi Terminal, a Raspberry Pi CM4-powered industrial HMI with a 7-inch touchscreen display. So instead of letting it go to waste, I decided to offer it as the second prize of the CNX Software Giveaway Week 2025 contest. Elecrow Pi Terminal specifications: SoM – Raspberry Pi CM4 Lite SoC – Broadcom BCM2711 CPU – Quad-core Cortex-A72 SoC @ 1.5GHz GPU – VideoCore VI with support for OpenGL ES 3.1 and Vulkan 1.0 VPU Decode – H.265/HEVC up to 4Kp60, H.264 up to 1080p60 Encode – H.264 up to 1080p30 Memory – 4GB LPDDR4-3200 Storage – N/A Wireless – Dual-band WiFi 5 and Bluetooth 5.0 Storage 64GB microSD card preloaded with the Raspberry Pi OS + Node-RED software M.2 […]

Giveaway Week 2025 – M5Stack Tab5 ESP32-P4 IoT devkit

It’s that time of the year when we organize CNX Software Giveaway Week, a global contest where we give away review samples or get companies to send units to readers. For the 12th edition of the contest, we have seven items to give away this time around: five review samples I will send myself, and two prizes from companies offering a router board and an industrial development kit. As usual, the contest is open worldwide, and CNX Software Thailand has a separate contest with four additional items for people with an address in Thailand. The first prize will be the M5Stack Tab5 ESP32-P4 IoT development kit featuring a 5-inch touchscreen display, a 2MP front-facing camera, a speaker, a dual-microphone array, a microSD card slot, an ESP32-C6 for wireless connectivity, sensors, and more. I had some fun reviewing the M5Stack Tab5 devkit by building the default firmware with the ESP-IDF framework, […]
