КП-74. Валидатор советской эпохи

Приветствую всех!

Уверен, даже если вы и не застали транспорт той эпохи, вы всё равно узнаете эти устройства — билетные компостеры. Если кассы ушли в историю значительно раньше, то вот они продержались много дольше, вплоть до конца девяностых, а кое-где и до двухтысячных.

Итак, сегодня мы взглянем на прямого предка электронных валидаторов. Посмотрим на тройку самых распространённых моделей и на то, как они устроены и как они кодировались, и разберёмся, как менялись эти девайсы со временем.

WiFi and Bluetooth LE can now be used simultaneously on Arduino boards with NINA-W102 (ESP32) module

Today I learned that WiFi and Bluetooth LE could NOT be used simultaneously on Arduino boards featuring the ESP32-based u-blox NINA-W102 wireless module, impacting the Arduino Nano RP2040 Connect, Arduino MKR WiFi 1010, and Arduino Nano 33 IoT boards. It’s a long-running problem since the first Arduino board with NINA-W10 was introduced in 2018, and meant you could use WiFi or Bluetooth LE, but not both simultaneously. The good news is that the issue has finally been fixed, thanks to a new firmware for the module and new WiFi and BLE libraries. More specifically, you’ll need the following libraries and...

STM32U3B5/C5 ultra-low-power MCU features 640 KB RAM, 2 MB Flash, and HSP accelerator to run AI without batteries

STMicroelectronics has added two members to the STM32U3 ultra-low-power Arm Cortex-M33 microcontroller family: the STM32U3B5 and STM32U3C5 MCUs get more resources with up to 640 KB SRAM and 2 MB flash, as well as an HSP (hardware signal processor) accelerator to run AI/ML workloads without batteries, just using energy harvesting. The new chips are still clocked at up to 96 MHz, benefit from a near-threshold design (down to 0.65 V), allowing a power consumption of just 117 Coremark/mW in active mode, and can operate up to 105°C ambient temperature. They come with one additional group of interfaces, bringing the total...

Plantower vs Sensirion — вскрываем лазерные датчики пыли

Ну штош. В этот раз о «железках».
Если вы когда-нибудь делали DIY-датчик воздуха — почти наверняка использовали датчики Plantower 5003 или Novafitness SDS011. Но сегодня мы вскроем Plantower PMS7003 и Sensirion SPS30.

Grinn ReneSOM-V2H is a tiny LGA SoM based on Renesas RZ/V2H processor for vision AI applications

Polish embedded systems company Grinn has recently introduced ReneSOM-V2H, a tiny vision AI SoM built around the Renesas RZ/V2H vision AI processor. Measuring just 42.6 x 37 mm, Grinn claims it is the world’s smallest module based on this specific Renesas MPU, and targets space-constrained Edge AI applications such as smart cameras, robotics, and industrial automation. The RZ/V2H SoC features a heterogeneous architecture with 4x Cortex-A55 cores, 2x Cortex-R8 cores, and 1x Cortex-M33 core, along with a DRP-AI3 accelerator with up to 8 TOPS. It supports LPDDR4 memory and eMMC storage, along with various connectivity options, including PCIe Gen3 (4-lane),...

ADLINK Express-PTL Panther Lake COM Express Type 6 module supports up to Intel Core Ultra 7 368H, 128GB DDR5

ADLINK Express-PTL COM Express Type 6 computer-on-module is built on Intel Core Ultra Series 3 “Panther Lake-H” SoCs up to the 16-core Core Ultra 7 368H processor delivering 180 TOPS of AI performance. The module pairs up to 128 GB DDR5 memory with IBECC support, features high-speed I/O such as PCIe Gen4, multiple display options, USB4/Thunderbolt capability, and industrial features such as TSN Ethernet, TPM 2.0, and advanced power management. As an industrial part, the Express-PTL is designed to operate across an extended –40°C to 85°C temperature range, and targets applications in robotics, industrial automation, medical imaging, transportation, and smart...

Checking out the actual AMD Ryzen SoC used on CHUWI CoreBook Air Plus 16 laptop

I’ve just completed the review of the CHUWI CoreBook Air Plus 16, a laptop based on an AMD Ryzen 5 6600H SoC. All software testing on Windows 11 Pro and Ubuntu 25.10 confirmed that the laptop was based on an AMD Ryzen 5 6600H SoC, but I was asked to confirm that the actual CPU on the motherboard was indeed the advertised chip, for reasons I’ll explain below. Let’s do that right now. I had already done a teardown of the laptop, but since the AMD Ryzen processor was covered by copper pipes for cooling, I could not read the...

Raspberry Pi CM5 industrial computer features RS485/RS232/CAN Bus/DIO interfaces, dual Ethernet, optional 4G/5G cellular module

Waveshare IPCBOX-CM5 is an industrial-grade mini computer built around the Raspberry Pi CM5, featuring RS485, RS232, CAN Bus, and DI/DO terminal blocks, dual Ethernet, an M.2 socket for NVMe SSDs or AI accelerators, and a wide 7V to 36V DC power input. The system is compatible with all CM5 variants and integrates GbE and 2.5GbE ports, a 4K-capable HDMI video output, multiple USB 3.2/2.0 ports, and an M.2 B-Key slot plus a Nano-SIM card slot for 4G LTE/5G cellular modules. Other features include microSD card support for Raspberry Pi CM5 Lite models, a PWM fan header, a buzzer, an audio...

NanoPi NEO3 Plus – A tiny Rockchip RK3528A headless SBC with Gigabit Ethernet, USB 3.0 port, GPIO header

FriendlyELEC NanoPi NEO3 Plus is an ultra-compact headless SBC powered by a Rockchip RK3528A SoC paired with 1GB RAM, whose main interfaces are a Gigabit Ethernet jack, a USB 3.2 port, and a 26-pin GPIO header. I can still remember using its predecessor, the NanoPi NEO3, based on a Rockchip RK3328, which I reviewed with Armbian in 2020. The new model is similar, with a quad-core Cortex-A53 SoC but clocked at 2.0 GHz instead of 1.5 GHz, and offered with a black metal case instead of a white plastic case. The OS can still be booted from a microSD card,...
