SC730 module from Small Computer Central features the now-discontinued Zilog Z80 CPU

SC730 RCBus Z80 CPU plus MMU Module

Small Computer Central has released a new module kit, the SC730, for the 80pin-RCBus backplane which features the widely-used 8-bit Zilog Z80 CPU and a memory management unit. The Zilog Z80 is an 8-bit microprocessor created to be compatible with the Intel 8080 microprocessor while offering more advanced features such as built-in DRAM refresh, a better interrupt system, and non-multiplexed buses. The Z80 microprocessor was widely used for various applications between the 70s and the 80s and is still quite popular among retro computing enthusiasts today. Cousins’ SC730 module kit is designed to fit into an 80-pin socket on an RCBus backplane. The module is built to be used with a memory module as part of a complete computer system. The memory management unit (MMU) is compatible with a 1MB linear memory module such as the SC721. It maps a fixed 32KB bank of RAM to the top of the […]

$4.99 ESP32-S3-Tiny board measures just 23.50 x 18 mm

waveshare esp32 s3 tiny kit a mini development board

Waveshare has recently released the ESP32-S3-Tiny mini development board powered by ESP32-S3 wireless MCU and measuring just 23.50 x 18 mm. Due to its compact form factor, it does not include a USB-to-UART converter or a USB port. That is why, you will need an additional adapter board with an FPC cable to program it, which costs only $1. Despite its small size, the board is feature-rich. It includes 34 multi-function GPIO pins, along with Wi-Fi, BLE, SPI, I2C, UART, ADC, PWM, and more. The design of the board is very similar to the Raspberry Pi RP2040-powered Waveshare RP2040-Tiny board that we covered last year. However, what sets this board apart is its 34 I/O pins, compared to the 23 found on the RP2040-Tiny board, and wireless connectivity. We’ve also written about several other boards with compact form factors, such as the Unexpected Maker NANOS3 board (28 x 11 mm), […]

Blues launches $19 Notecard XP cellular IoT module and Notecarrier XP series carrier board

Blues $19 Notecard XP

Blues has recently released the latest entry to its Notecard family, the Notecard XP (External Power supply), an updated and more cost-effective version of its existing Notecard Cellular. This new model reduces costs by not including certain components, such as SIM switching hardware, an embedded SIM with a data plan, and conformal coating while retaining all key features and functionalities. These include an Arm Cortex-M4 microcontroller, a three-axis accelerometer, a temperature sensor, and a secure element. Additionally, they have also removed the radio power supply to reduce costs further, bringing the price down to just $19. Alongside this release, Blues has also introduced a new “midband” LTE Cat 1 bis Notecard Cellular model, which features a single antenna design making it more compact and economical. In February this year we have seen Blues announced the Blues Starnote IoT Module, along with the Notecarrier A, B, F, and Pi series of […]
