It’s time to say goodbye to the SIM800C GSM module, which has been in production for 11 years, since 2015.
 We regret to inform you that the production of these modules will soon be discontinued.
 Please take care of your SIM800C stock during the transition to modern module models.
 Orders for the purchase of the modules you need will be accepted until August 2026.
 Further delivery will be impossible due to the lack of chipsets used.

 We would like to inform you that popular LCD indicators - RC2004A-YHY-CSX - are available again from stock.
 Character, 20x4, 98.0x60.0, 4/8 Bit interface, yellow-green backlight.
 The most common application is charging stations for electric vehicles.

  For details, contact our specialists.

 SIMCOM, a manufacturer of cellular and navigation modules, informs that due to a significant increase in memory prices, it will review module prices.
 This applies to modules where the memory chip is installed separately - 4G, 5G, SMART.
 Modules where the memory is integrated into the chipset (2G) will remain at the old prices for now.

 We bring to your attention the article: "Strategies for the comprehensive protection of Li-ion batteries", which was published in the 5th issue of the CHIP NEWS magazine (www.chipnews.com.ua) for 2025.

 The article discusses the main mechanisms for protecting lithium-ion and lithium-polymer batteries, and also highlights the solutions offered by Fuzetec to protect against typical malfunctions.

 You can read this and other articles in the 5th issue of the CHIP NEWS magazine for 2025, which is published electronically and is freely available.

 We would like to inform you that the production time of SIM800C modules has been extended until the end of 2027.

 We remind you that the production and delivery time is about 12 weeks.

 Place your orders and submit your needs in advance.

 We present to you the new wireless module LoRa-STM32WLE5.
 Provides long-range communication (up to 5 km.), and ultra-low consumption.


 The LoRa-STM32WLE5 module uses the STM32WLE5 microcontroller, which contains a 32-bit RISC-core Arm® Cortex-M4® + DSP with a clock frequency of up to 48 MHz, 256 KB of flash memory and 64 KB of RAM. It has an independent memory protection unit (MPU) and AES-256 hardware encryption to increase application security.
 Developers have access to I/O ports and standard interfaces - UART, SPI, I2C, GPIO, ADC.
 The module is designed for applications in security systems, industrial production, smart home solutions, metering devices, etc.

 If you lack the performance of the MCS-51 core, we recommend considering the M2003 microcontroller series to replace the N76E003, N76S003.
