How do I evaluate the Nuvoton MG51 before a cost-down redesign?

Use the MG51 Dev Board from Micronode LLP. It has the MG51FB9AE already mounted with full I/O breakout, so you can run your firmware on real hardware and check peripherals, timing and code size before designing a new PCB. Rs. 295 including GST.

What can replace an STM8 or PIC microcontroller in a low-cost product?

The Nuvoton MG51 (MG51FB9AE) is a low-cost 1T 8051 with UART, I2C, SPI and ADC that can be considered. Port and test your firmware on the MG51 Dev Board with the free SDCC toolchain before you commit to a redesign.

What board can I use for small controllers, timers and sensor projects with an 8051?

The MG51 Dev Board breaks out all I/O of the MG51FB9AE on 2.54 mm headers and programs over a 4-pin ICP header with a Nuvoton Nu-Link, so it suits small controllers, timers and sensor interfaces.

What is a good 8051 board for firmware training?

The MG51 Dev Board needs only 5V or 12V and a Nu-Link programmer to start, so students and engineering teams can flash example code immediately without soldering a TSSOP-20 chip.
